[PATCH 1/1] dm-integrity: Remove unreachable code in dm_integrity_ctr()

[Ivan Abramov]

Since bi->metadata_size is an unsigned char, it's not practically
possible for it to be > PAGE_SIZE / 2.

Thus, remove the corresponding if statement.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
