drm/amdgpu/mes: zero the sdma_hqd_mask of 2nd SDMA engine for SDMA 6.0.1 

[ Upstream commit 0af4ed0c32 ]

there is only one SDMA engine in SDMA 6.0.1, the sdma_hqd_mask has to be
zeroed for the 2nd engine, otherwise MES scheduler will consider 2nd
engine exists and map/unmap SDMA queues to the non-existent engine.
