irq_work.h: fix warning when CONFIG_IRQ_WORK=n



A randconfig caught repeated compiler warnings when CONFIG_IRQ_WORK=n
due to the definition of a non-inline static function in
<linux/irq_work.h>:

  include/linux/irq_work.h +40 : warning: 'irq_work_needs_cpu' defined but not used

Make it inline to supress the warning.  This is caused commit
00b42959 ("irq_work: Don't stop the tick with pending works") merged
in v3.9-rc1.
