drm/amdgpu: Fix reset_hw_queue on MES 12.1

Browse source

Different from detect_and_reset, reset_hw_queue performs per queue
reset. Per queue reset setting requires reset_queue_only=1 and hung
queue's doorbell_offset in RESET packet. This packet must be sent to MES
pipe 0(SCHED_PIPE).

We also need to set enable_compute_pipe_reset=1 in SET_HW_RESOURCES so
when queue reset fails, MES will proceed pipe reset.

This patch also fixes a bug in mes_v12_1_reset_hw_queue function. Instead
of using MESAPI__RESET offset for api_status, the existing code uses
MESAPI__REMOVE_QUEUE.
