drm/amdkfd: Use drm_priv to pass VM from KFD to amdgpu

Browse Source 
commit b40a6ab2cf upstream.

amdgpu_amdkfd_gpuvm_alloc_memory_of_gpu needs the drm_priv to allow mmap
to access the BO through the corresponding file descriptor. The VM can
also be extracted from drm_priv, so drm_priv can replace the vm parameter
in the kfd2kgd interface.
