drm/panthor: Interrupt group start/resumption if group_bind_locked() fails
group_bind_locked() can fail if the MMU block is stuck. This is normally
a reset situation, but by the time we reset the GPU, we might have
tried to resume a group that's not resident, which will probably trip
out the FW. So let's avoid that by bailing out when group_bind_locked()
returns an error. We don't even try to start more groups because the
GPU will be reset anyway.
