[PATCH 4/5] media: coda: Remove pic_run_work worker

[Ezequiel Garcia <ezequiel@collabora.com>]

There isn't any reason to run the mem2mem job on a separate worker,
because the mem2mem framework guarantees that device_run will never
run in interrupt context.

Therefore, get rid of the extra pic_run_work worker, and instead
run the job in the context of .device_run itself.
