Arnd Bergmann bbe9a70a47 tick-sched: avoid a maybe-uninitialized warning 
The use of bitfields seems to confuse gcc, leading to a false-positive
warning in all compiler versions:

kernel/time/tick-sched.c: In function 'tick_nohz_idle_exit':
kernel/time/tick-sched.c:538:2: error: 'now' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This introduces a temporary variable to track the flags so gcc
doesn't have to evaluate twice, eliminating the code path that
leads to the warning.

Fixes: 1cae544d42d2 ("nohz: Gather tick_sched booleans under a common flag field")
