srcu: Allow inlining of __srcu_read_{,un}lock_lite()
This commit moves __srcu_read_lock_lite() and __srcu_read_unlock_lite()
into include/linux/srcu.h and marks them "static inline" so that they
can be inlined into srcu_read_lock_lite() and srcu_read_unlock_lite(),
respectively. They are not hand-inlined due to Tree SRCU and Tiny SRCU
having different implementations.
The earlier removal of smp_mb() combined with the inlining produce
significant single-percentage performance wins.
