device_cgroup: don't grab mutex in rcu callback
commit 103a197 ("security/device_cgroup: lock assert fails in
dev_exception_clean()") grabs devcgroup_mutex to fix assert failure, but
mutex can't be grabbed in rcu callback. Since there shouldn't be any
other references when css_free is called, mutex isn't needed for list
cleanup in devcgroup_css_free().
