[PATCH v6 2/8] drm/amdgpu/userq: Fix the mutex_init cleanup for fence_drv_lock

[Sunil Khatri <sunil.khatri@amd.com>]

mutex fence_drv_lock is destroyed in amdgpu_userq_fence_driver_free
also in one of the jump condition mutex_destroy is also called leading
to double mutex_destroy.

So rearranging the code so amdgpu_userq_fence_driver_free takes care
of the clean up along with mutex_destroy.
