block: Fix elevator_get_default() checking for NULL q->tag_set

Browse Source 
[ Upstream commit b402328a24 ]

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.
