Christoph Hellwig dd6f7f17bf block: add proper helpers for elevator_type module refcount management ...

Make sure we have helpers for all relevant module refcount operations on
the elevator_type in elevator.h, and use them.  Move the call to the get
helper in blk_mq_elv_switch_none a bit so that it is obvious with a less
verbose comment.
