Eric Dumazet a8e998dd14 posix-timers: Add cond_resched() to posix_timer_add() search loop ...

[ Upstream commit 5f2909c6cd13564a07ae692a95457f52295c4f22 ]

With a large number of POSIX timers the search for a valid ID might cause a
soft lockup on PREEMPT_NONE/VOLUNTARY kernels.

Add cond_resched() to the loop to prevent that.
