Subject: [PATCH next] accel/rocket: Fix some error checking in
 rocket_core_init()

The problem is that pm_runtime_get_sync() can return 1 on success so
checking for zero doesn't work.  Use the pm_runtime_resume_and_get()
function instead.  The pm_runtime_resume_and_get() function does
additional cleanup as well so that's a bonus as well.

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