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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
