    drm: fix deadlock of syncobj v6

    v2:
    add a mutex between sync_cb execution and free.
    v3:
    clearly separating the roles for pt_lock and cb_mutex (Chris)
    v4:
    the cb_mutex should be taken outside of the pt_lock around
    this if() block. (Chris)
    v5:
    fix a corner case
    v6:
    tidy drm_syncobj_fence_get_or_add_callback up. (Chris)

    Tested by syncobj_basic and syncobj_wait of igt.
