Tom St Denis 22d6575b8d 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
