dm-integrity: set discard_granularity to logical block size
commit 69381cf88a8dfa0ab27fb801b78be813e7e8fb80 upstream.
dm-integrity could set discard_granularity lower than the logical block
size. This could result in failures when sending discard requests to
dm-integrity.
This fix is needed for kernels prior to 6.10.
