drm/nouveau/fifo/gk104-: fix parsing of mmu fault data
...
Pascal was particularly incorrect, as the register changed to be more in the
same format as the MMU fault buffers are.
Shouldn't have impacted much more than confusing MMU fault log messages.

drm/nouveau/fifo/gf100-: recover from host mmu faults
...
This has been on the TODO list for a while now, recovering from things
such as attempting to execute a push buffer or touch a semaphore in an
unmapped memory area.
The only thing required on the HW side here is that the offending
channel is removed from the runlist, and *not* a full reset of PFIFO.
This used to be a bit messier to handle before the rework to make use
of engine topology info, but is apparently now trivial.
