[PATCH] drm: remove unnecessary fault wrappers

[Ross Zwisler]

The fault wrappers drm_vm_fault(), drm_vm_shm_fault(), drm_vm_dma_fault()
and drm_vm_sg_fault() used to provide extra logic beyond what was in the
"drm_do_*" versions of these functions, but as of this commit:

commit ca0b07d9a969 ("drm: convert drm from nopage to fault.")

They are just unnecessary wrappers that do nothing.  Remove them.
