[PATCH v2 1/3] accel/rocket: Don't tear down the scheduler when drm_sched_init() fails

[Sidong Yang]

drm_sched_init() cleans up after itself when it fails, but
rocket_job_init() then calls drm_sched_fini() on the same scheduler.
That wakes a wait queue that was never initialised, dereferencing a
NULL pointer, and can destroy the submit workqueue a second time.

Only destroy the reset workqueue on this path.

Fixes: 0810d5ad88a1 ("accel/rocket: Add job submission IOCTL")
