dm flakey: error READ bios during the down_interval
commit 99f3c90d0d85708e7401a81ce3314e50bf7f2819 upstream.
When the corrupt_bio_byte feature was introduced it caused READ bios to
no longer be errored with -EIO during the down_interval. This had to do
with the complexity of needing to submit READs if the corrupt_bio_byte
feature was used.
Fix it so READ bios are properly errored with -EIO; doing so early in
flakey_map() as long as there isn't a match for the corrupt_bio_byte
feature.
Fixes: a3998799fb4df ("dm flakey: add corrupt_bio_byte feature")
