rcu: Replace open-coded rcu_exp_need_qs() from rcu_exp_handler() with call

Browse source

Currently, the preemptible implementation of rcu_exp_handler()
almost open-codes rcu_exp_need_qs().  A call to that function would be
shorter and would improve expediting in cases where rcu_exp_handler()
interrupted a preemption-disabled or bh-disabled region of code.
This commit therefore moves rcu_exp_need_qs() out of the non-preemptible
leg of the enclosing #ifdef and replaces the open coding in preemptible
rcu_exp_handler() with a call to rcu_exp_need_qs().
