Subject: [PATCH 2/5] jump_label: also include linux/atomic.h when jump label is enabled

The struct static_key will have a atomic_t type member no matter
whether jump label is enabled or not. We would include linux/atomic.h
when jump label is not enabled. But it also does make sense to include
this header file when jump label is enabled.
