[PATCH 30/88] target/pscsi: Fix page increment

[Luis Henriques]

3.5.7.8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Asias He <asias at redhat.com>

commit 472b72f2db7831d7dbe22ffdff4adee3bd49b05d upstream.

The page++ is wrong. It makes bio_add_pc_page() pointing to a wrong page
address if the 'while (len > 0 && data_len > 0) { ... }' loop is
executed more than one once.
