Subject: UBI: account for bitflips in both the VID header and data

From: Brian Norris <computersforpeace@gmail.com>

commit 8eef7d70f7c6772c3490f410ee2bceab3b543fa1 upstream.

We are completely discarding the earlier value of 'bitflips', which
could reflect a bitflip found in ubi_io_read_vid_hdr(). Let's use the
bitwise OR of header and data 'bitflip' statuses instead.

Coverity CID #1226856
