rcu-tasks: Always inline rcu_irq_work_resched()
[ Upstream commit 6309a5c43b0dc629851f25b2e5ef8beff61d08e5 ]
Thanks to CONFIG_DEBUG_SECTION_MISMATCH, empty functions can be
generated out of line. rcu_irq_work_resched() can be called from
noinstr code, so make sure it's always inlined.
Fixes: 564506495ca9 ("rcu/context-tracking: Move deferred nocb resched to context tracking")
