[PATCH 1/5] UBI: account for bitflips in both the VID header and data

[Brian Norris]

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
