[PATCH 1/2] drm/amdgpu: Fix per queue reset on MES 12.1

[Amber Lin <amber.lin@amd.com>]

Different from detect_and_reset, reset_hw_queue performs per queue reset
by sending reset_queue_only=1 and hung queue's doorbell_offset to MES
in RESET packet. enable_compute_pipe_reset=1 also needs to be set in
SET_HW_RESOURCES so when queue reset fails, MES will proceed pipe reset.

This patch also fix 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.
