block: Make the integrity mapped property a bio flag
Previously we tracked whether the integrity metadata had been remapped using a request flag. This was fine for low-level retries. However, if an I/O was redriven by upper layers we would end up remapping again, causing the retry to fail. Deprecate the REQ_INTEGRITY flag and introduce BIO_MAPPED_INTEGRITY which enables filesystems to notify lower layers that the bio in question has already been remapped. Signed-off-by: Martin K.
