Felix Kuehling 094073ff74 Revert "libhsakmt: Try to use CPU addr as GPU addr for userptrs" ...

This reverts commit 84bb9072c0.

This fixes ambiguity when looking up GPU addresses with
hsaKmtQueryPointerInfo.

hsa_amd_agents_allow_access uses hsaKmtQueryPointerInfo, and
depends on finding the correct object from a GPU address. Finding
the wrong userptr object based on its CPU address leads to
incorrect GPU mappings and results in VM faults.
