blkcg: drop local variable @q from blkg_destroy()

blkg_destroy() caches @blkg->q in local variable @q.  While there are
two places which needs @blkg->q, only lockdep_assert_held() used the
local variable leading to unused local variable warning if lockdep is
configured out.  Drop the local variable and just use @blkg->q
directly.
