UCX test cases are reporting uninitialized values when CMA fails. The
application should ideally ignore SizeCopied when the function fails but
it doesn't. This is leading to wrong diagnosis.
v2: Fill in partial SizeCopied in case of failure

This reverts commit f7689d4fef,
Plus a bug fix to patch "Cleanup fmm.c":
Call id_in_array with correct parameter. The third parameter
of id_in_array is size in byte of the array, not the number
of array items. Call it correctly.

to fmm_allocate_memory_object. This function name was confusingly
similar to fmm_allocate_device and __fmm_allocate_device. The new name
reflects its function better: allocate the VM object and the kernel
mode buffer object.

Prefer using memfd_create() for the ring buffer.
We were using /dev/shm, but this won't work on systems that
either don't have /dev/shm or have mounted it with noexec, because
for everything other than gfx700 we map the ring buffer with PROT_EXEC.
memfd_create() is Linux specific and was added in Linux 3.17, so we
will fallback to using /dev/shm on systems where memfd_create() is
not available.

Corrected semantics used in hsa_queue_load_write_index_relaxed.
The semantics that was used in hsa_queue_load_write_index_relaxed
didn't seem to match the name of the function.
I also removed a useless return keyword.

1. Renamed _fmm_map_to_gpu to _fmm_map_to_apu_local
to reflect the real semantics of this function
2. Renamed _fmm_map_to_gpu_gtt to _fmm_map_to_gpu
because this function is used to map both gtt
and local memory
3. Call _fmm_map_to_gpu in _fmm_map_to_apu_local
to get rid of duplicated codes

_fmm_unmap_from_gpu is called in fmm_map_to_gpu_nodes
to unmap buffer from nodes that is already mapped to
but not in the new map nodes list. Previously, the unmap
was called unconditionally even though the size of the
array to unmap is 0. This fixes the issue by calling
the unmap func only when the unmap array size is not 0.
Also releases the fmm_mutex on error returns

Buffer mapping to devices and buffer registration to
devices can be changed b/t two pointer info queries.
Thus update buffer mapping info and registration info
only when mapping and registration changed. This is
done by free mapped_node_id_array on mapping to new
device and free registered_node_id_array on registration
and re-allocate them on next ptr info query.
Also uses fmm_mutex to avoid race conditions in case
of calling hsaKmtQueryPointerInfo concurrently with
calling of buffer mapping or registration
