drm/amd/amdgpu: add missing mutex lock to amdgpu_get_xgmi_hive() (v3)
v2: Move locks around in other functions so that this
function can stand on its own. Also only hold the hive
specific lock for add/remove device instead of the driver
global lock so you can't add/remove devices in parallel from
one hive.
v3: add reset_lock
