drm/amdgpu: destroy mutex when tearing down ttm buffer entity

Browse source

Pair mutex_init() with mutex_destroy() on the GART window allocation
failure path and in amdgpu_ttm_buffer_entity_fini(). This is a no-op
without CONFIG_DEBUG_MUTEXES, but it keeps lockdep from seeing a live
mutex after the entity is freed or re-initialized.
