bio-integrity: update the payload size in bio_integrity_add_page()
Previously, the bip's bi_size has been set before an integrity pages
were added. If a problem occurs in the process of adding pages for
bip, the bi_size mismatch problem must be dealt with.
When the page is successfully added to bvec, the bi_size is updated.
The parts affected by the change were also contained in this commit.
