If hsa_amd_agents_allow_access is called for an imported IPC handle,
ignore the request as this pointer will already have these pointers
mapped to other GPUs during IPCAttach()

If a user queries the pointer info on an invalid pointer,
hsaKmtQueryPointerInfo will return error or unknown pointer. The other
fields in HsaPointerInfo are invalid, so we do not return them to the
user.
Also removing the assert and returning unknown pointer instead. As the
assert will not trigger in release builds.
hsaKmtQueryPointerInfo may also return unknown pointer for userptrs as
they are not always tracked by thunk. Adjusting code to still treat
these pointers as valid in this case.

Amount of memory requested by user may be aligned-up internally to

The allocation logic of the SPI does not take into account compute
user thread management settings for masking CUs with the exception of
skipping fully disabled SEs. This means that occupancy limited
dispatches such as cooperative launch may over allocate onto hardware
resources that are not immediately available, resulting in a potential
barrier logic hang as occupying work groups are waiting on enqueued
work groups to reach the barrier.
Further work will have to be done to get the per-SA CU enablement count
from the KFD in order to correctly clip the cooperative CU limit based
on the CU mask, which will require breaking the current ABI.
For now, report that cooperative launch is not supported while a CU
mask has been applied to prevent potential shader hangs.

GPUs excluded by RVD are not expected to have scratch, memory, trap
handling nor memory regions set up. Now that these GPUs are added to
a new list, early return on agent destruction to prevent bad function
calls on destroy.
Also fix up broken memory releases between the gpu lists and ugly braces.

Discovered agent handles should only apply to copy routing, not to
copy device selection. The user may not have mapped all allocations
to all GPUs so we must ensure that the copying device is one passed
by the user.

Hive ID is used during copy path selection to locate an optimal
pool of SDMA engines. However, for CPU-GPU connections we always
want to use the host port facing engines, known generally as the
PCIe optimzed engines. We want this selection even when the
connection is XGMI hence dropping the hive id for CPUs.
