When dispatch_rq_from_ctx is called, in the vast majority of cases

I'm fine with killing it, generally I dislike the likely/unlikely
annotations unless the intent is absolutely clear. This one is not.

Fixes: b347689ffbca ("blk-mq-sched: improve dispatching from sw queue")

Though for this one, I'll drop the fixes tag as it isn't something we
need to backport to stable and it's not really fixing a real bug that
is causing an issue.
