Subject: [PATCH]:drivers/md/raid10.c: r10buf_pool_alloc(): Set bi_vcnt for the
 new bio.

Hi Neil,
raid10.c: r10buf_pool_alloc() - doesn't set the bi_vcnt for the newly
allocated bio. Setting it to RESYNC_PAGES for successful case.

BTW, why are we not using bio_add_page() here to add the page to bio?
