[PATCH] accel/rocket: fix ignored return value in rocket_ioctl_submit

[Kartik Nair]

rocket_ioctl_submit() calls rocket_ioctl_submit_job() in a loop but
ignores its return value. If any job submission fails, the error is
silently dropped and the function returns 0 (success) to userspace,
leaving subsequent jobs potentially in an inconsistent state.

Fix this by propagating the error and breaking out of the loop on
the first failure.
