[PATCH 3/4] timerfd: Factor out timer-type unspecific timerfd_expire()

[Anton Vorontsov <anton.vorontsov@linaro.org>]

There is nothing hrtimer-specific inside the timerfd_tmrproc(), except
the function prototype. We're about to add other timer types, so factor
out generic timerfd_expire() helper from timerfd_tmrproc().
