Seema Khowala 5d2058791f gpu: nvgpu: acquire/release runlist_lock during teardown/mmu_fault ...

-Recovery can be called for various types of faults. Acquire
 runlist_lock for all runlists so that current teardown is done
 before proceeding to next one.
-For legacy chips teardown is done by triggering mmu fault so
 make sure runlist_locks are acquired during teardown and also
 during handling mmu fault.
-gk20a_fifo_handle_mmu_fault is renamed as
 gk20a_fifo_handle_mmu_fault_locked
-gk20a_fifo_handle_mmu_fault called from gk20a_fifo_teardown_ch_tsg
 is replaced with gk20a_fifo_handle_mmu_fault_locked
-gk20a_fifo_handle_mmu_fault acquires/release runlist_lock for all
 runlists and calls gk20a_fifo_handle_mmu_fault_locked
