block: move queue freezing & elevator_lock into elevator_change()
Move queue freezing & elevator_lock into elevator_change(), and prepare
for using elevator_change() for setting up & tearing down default elevator
too.
Also add lockdep_assert_held() in __elevator_change() because either
read or write lock is required for changing elevator.
