Revert "drm/msm: Fix failure paths in msm_drm_init()"
This reverts commit 8636500300a01740d92b345c680b036b94555b1b.
A recent commit tried to address a drm device leak in the early
msm_drm_uninit() error paths but ended up making things worse.
Specifically, it moved the drm device reference put in msm_drm_uninit()
to msm_drm_init() which means that the drm would now be leaked on normal
unbind.
For reasons that were never spelled out, it also added kms NULL pointer
checks to a couple of helper functions that had nothing to do with the
paths modified by the patch.
Instead of trying to salvage this incrementally, let's revert the bad
commit so that clean and backportable fixes can be added in its place.
