gpu: nvgpu: recover on first interrupt reported for mmu nack
In case of mmu nack error interrupt is received twice through SM
reported mmu nack interrupt and mmu fault in undertermined order.
Recover on the first received interrupt to avoid semaphore release
and skip doing a second recovery.
Also fix NULL pointer dereference in function
gv11b_fifo_reset_pbdma_and_eng_faulted when channel reference is
invalid in teardown path.
