[ Upstream commit b402328a24ee7193a8ab84277c0c90ae16768126 ]
elevator_get_default() and elv_support_iosched() both check for whether or not q->tag_set is non-NULL, however it's not possible for them to be NULL. This messes up some static checkers, as the checking of tag_set isn't consistent.
Remove the checks, which both simplifies the logic and avoids checker errors.
