Subject: [PATCH] drm/amdgpu: address the static checker warnings V2

drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:4199 amdgpu_device_gpu_recover()
error: we previously assumed 'hive' could be null (see line 4196)

This is introduced by "drm/amdgpu: optimize the gpu reset for XGMI setup V2".

V2: drop this mutex release needed for XGMI since XGMI never fails on
    this
