srcu: Remove smp_mb() from srcu_read_unlock_lite()
The srcu_read_unlock_lite() function invokes __srcu_read_unlock() instead
of __srcu_read_unlock_lite(), which means that it is doing an unnecessary
smp_mb(). This is harmless other than the performance degradation.
This commit therefore switches to __srcu_read_unlock_lite().
