Subject: [PATCH] dm-integrity: fix a typo in the code for write/discard race

If we send a write followed by a discard, it may be possible that the discarded data end up being overwritten by the previous write from the journal. The code tries to prevent that, but there was a typo in this logic that made it not being activated as it should be.

Note that if we end up here the second time (when discard_retried is true), it means that the write bio is actually racing with the discard bio, and in this situation it is not specified which of them should win.
