UBI: account for bitflips in both the VID header and data
[ Upstream commit 8eef7d70f7c6772c3490f410ee2bceab3b543fa1 ]
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.
