drm/nouveau: Avoid lock dependency between ramht and ramin spinlocks.
...
The ramht code called some gpuobj functions with the HARDIRQ-safe
RAMHT spinlock held, this could potentially lead to a dead lock
because ramin_lock is HARDIRQ-unsafe.

drm/nouveau: protect ramht_find() from oopsing if on channel without ramht
...
This doesn't actually happen now, but there's a test case for an earlier
kernel where a GPU error is signalled on one of nv50's fake channels, and
the ramht lookup by the IRQ handler triggered an oops.
This adds a check for RAMHT's existance on a channel before looking up
an object handle.
