Writeback jobs are allocated when the WRITEBACK_FB_ID is set, and
deleted when the jobs complete. This results in both a memory leak of
the job and a leak of the framebuffer if the atomic commit returns
before the job is queued for processing, for instance if the atomic
check fails or if the commit runs in test-only mode.
Fix this by implementing the drm_writeback_cleanup_job() function and
calling it from __drm_atomic_helper_connector_destroy_state(). As
writeback jobs are removed from the state when they're queued for
processing, any job left in the state when the state gets destroyed
needs to be cleaned up.
The existing declaration of the drm_writeback_cleanup_job() function
without an implementation hints that this problem was considered, but
never addressed.

Somehow the code to put the damage blob on destroy plane state and set
the blob to NULL when duplicate plane state was not merged. May be
because the files are refactored since the patch was written. With this
fix add those.

I've misplaced two functions by accident:
- drm_atomic_helper_duplicate_state is really part of the
resume/suspend/shutdown device-wide helpers.
- drm_atomic_helper_legacy_gamma_set is part of the legacy ioctl
compat helpers.
Move them both back.
