[PATCH] drm/etnaviv: avoid cleaning up sched_job when submit succeeded

[Lucas Stach]

While the labels may mislead the casual reader, the tail of the function
etnaviv_ioctl_gem_submit is always executed, as a lot of the structures
set up in this function need to be cleaned up regardless of whether the
submit succeeded or failed.

An exception is the newly added drm_sched_job_cleanup, which must only
be called when the submit failed before handing the job to the
scheduler.
