Lucas Stach 1396500d67 drm/etnaviv: lock MMU while dumping core 
The devcoredump needs to operate on a stable state of the MMU while
it is writing the MMU state to the coredump. The missing lock
allowed both the userspace submit, as well as the GPU job finish
paths to mutate the MMU state while a coredump is under way.
