Maíra Canal b464edc12d drm/etnaviv: Protect the scheduler's pending list with its lock ...

commit 61ee19dedb8d753249e20308782bf4e9e2fb7344 upstream.

Commit 704d3d60fe ("drm/etnaviv: don't block scheduler when GPU is still
active") ensured that active jobs are returned to the pending list when
extending the timeout. However, it didn't use the pending list's lock to
manipulate the list, which causes a race condition as the scheduler's
workqueues are running.

Hold the lock while manipulating the scheduler's pending list to prevent
a race.
