Thomas Fleury 5e688c35f8 gpu: nvgpu: set error notifier in SW quiesce ...

For MMU and PBDMA faults, error notifier needs to be set
before entering SW quiesce. Otherwise it ends up with
default NVGPU_ERR_NOTIFIER_FIFO_ERROR_IDLE_TIMEOUT.

Added nvgpu_rc_mmu_fault to:
- call g->ops.fifo.recover when recovery is enabled
- set MMU error when recovery is disabled

Updated nvgpu_rc_pbdma_fault to set PBDMA error when
recovery is disabled as well.

Wait for deferred interrupts to complete before actually
entering SW quiesce state, to make sure error notifier has
been set.

Jira NVGPU-4127
