drm/scheduler: Rename cleanup functions v2.

Everything in the flush code path (i.e. waiting for SW queue
to become empty) names with *_flush()
and everything in the release code path names *_fini()

This patch also effect the amdgpu and etnaviv drivers which
use those functions.

v2:
Also pplay the change to vd3.
