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, and
rename the the drm_do_* fault handlers to remove the "do_" since they no
longer have corresponding wrappers.

This patch applies cleanly to mmots/master, which is currently at
v4.10-rc5-mmots-2017-01-26-15-49.
