hrtimer.h: prevent pinned timer state from breaking inactive testlinux-lng-3.14.12-2014.09linux-lng-v3.14.x
An hrtimer may be pinned to a CPU but inactive, so it is no longer valid
to test the hrtimer.state struct member as having no bits set when inactive.
Changed the test function to mask out the HRTIMER_STATE_PINNED bit when
checking for inactive state.
