drm/vgem: Drop vgem_drm_gem_mmap
It's duplicating (without using some of the helpers) drm_gem_mmap with the addition that it can redirect to drm-buf mmap support. But prime import/export was dropped in commit 990ed272 Author: Rob Clark <robdclark@gmail.com> Date: Thu May 21 11:58:30 2015 -0400 drm/vgem: drop DRIVER_PRIME (v2) for now, so this is dead code. And since I want to rework the locking for drm_gem_mmap it seems simpler to de-dupe this code for now and then start over with the reworked one again, if we want to resurrect this all indeed.
