Felix Kuehling 84bb9072c0 libhsakmt: Try to use CPU addr as GPU addr for userptrs ...

If the CPU addr of a userptr is accessible by the GPU, try to use it
instead of allocating a different GPU address. If something else is
already registered with an overlapping address range, we still need to
allocate a GPU address, because KFD does not support overlapping GPUVM
mappings.
