drm/msm: Fix error handling crashes seen when VRAM allocation fails ...
If VRAM allocation fails, the error handling path crashes in
msm_drm_uninit(). The following changes are made to fix this:
msm_gem_shrinker_cleanup() is fixed to unregister the shrinker only
if it was init-ed in the first place.
Before calling kms->funcs->destroy(), we check if kms->funcs is also
non-NULL. This is needed for MDP5, since during msm_drm_int(), priv->kms
becomes non-NULL early, but msm_kms_init() is called on it only later
in mdp5_kms_init().
