[PATCH 5/5] time: Add missing annotation for __run_timer()

[Jules Irenge]

Sparse reports a warning at __run_hrtimer()

|warning: context imbalance in __run_hrtimer() - unexpected unlock

To fix this, a must_hold() annotation is added.
Given that __run_hrtimer() requires lock to be held
This  not only fixes the warning
but also improves on the readability of the code.
