timer: Clear deferrable_pending while handling timer softirq
Clear deferrable_pending everytime timer softirq is run.
This handles a potential race condition, where one CPU
handles all deferrable timers, before the other CPU gets
a change to run timer softirq. Due to the deferrable_pending
not getting cleared, subsequently, CPUs do not raise
the softirq for handling expired deferrable timers,
in nohz idle enter path.
