gpu: nvgpu: separate API to get failing engine data

In gk20a_fifo_handle_sched_error(), we currently have a sequence
to identify failing engine (stuck on context switch) and
corresponding failing channel with its type

Separate out this sequence in new API
gk20a_fifo_get_failing_engine_data() so that it can be
reused from else where too
