block/mq-deadline: Remove some unused functions

These functions are defined in the mq-deadline.c file, but not called
elsewhere, so delete these unused functions.

block/mq-deadline.c:134:1: warning: unused function 'deadline_earlier_request'.
block/mq-deadline.c:148:1: warning: unused function 'deadline_latter_request'.
