accel/amdxdna: Preserve user address when PASID is disabled

When PASID is not used, the buffer user address is set to
AMDXDNA_INVALID_ADDR. As a result, heap buffer user address validation
fails even though the original userspace address is available.

Preserve the userspace address regardless of PASID usage so heap buffer
address validation works correctly.
