Ming Lei d63be5f924 PM / Runtime: fix recursive locking warning of lockdep from rpm_resume()
For device with no_callbacks flag set, its power lock and its parent's
power lock may be held nestedly in rpm_resume, so we should take
spin_lock_nested(lock, SINGLE_DEPTH_NESTING) to acquire parent power lock
to avoid lockdep warning.
