gpu: nvgpu: improve sched err handling

bug 200114561

1) when handling sched error, if CTXSW status reads switch
check FECS mailbox register to know whether next or current
channel caused error
2) Update recovery function to use ch id passed to it
3) Recovery function now passes mmu_engine_id to mmu fault
handler instead of fifo_engine_id
