[PATCH v2 3/3] accel/rocket: Propagate job submission errors

[MoGGuU]

rocket_ioctl_submit() discards each job's return value and reports success
even when every job fails.

Return the first error and stop submitting the remaining jobs. Jobs queued
before an error remain queued, giving the ioctl ordered partial-submit
semantics.

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