block: mq-deadline: Rename deadline_is_seq_writes()

Rename deadline_is_seq_writes() to deadline_is_seq_write() (remove the
"s" plural) to more correctly reflect the fact that this function tests
a single request, not multiple requests.

Fixes: 015d02f4 ("block: mq-deadline: Do not break sequential write streams to zoned HDDs")
