drm/amdgpu: Consolidate ctx put

Browse source

Currently there are two flavours of the context reference count
destructor:

 - amdgpu_ctx_do_release(), used from kref_put from places where the code
   thinks context may have been used, or is in active use, and;
 - amdgpu_ctx_fini(), used when code is sure context entities have already
   been idled.

Since amdgpu_ctx_do_release() calls amdgpu_ctx_fini() after having idled
and destroyed the scheduler entities, we can consolidate the two into a
single function.

Functional difference is that now drm_sched_entity_destroy() is called on
context manager shutdown (file close), where previously it was
drm_sched_entity_fini(). But the former is a superset of the latter, and
during file close the flush method is also called, which calls
drm_sched_entity_flush(), which is also called by
drm_sched_entity_destroy(). And as it is safe to attempt to flush a never
used entity, or flush it twice, there is actually no functional change.
