V4L/DVB (10853): cx18: Fix s-parse warnings and a logic error about extracting the VBI PTS
My s-parse builds never griped about be32_to_cpu() casting to __be32, but Hans'
builds did. This change explictly declares the pointer into the VBI buffer
header as __be32, which is the correct thing to do as the data is always
big endian when we go to fetch it. Hopefully this will quiet s-parse warnings.
Also corrected a misplaced parenthesis logic error in checking for the VBI
header magic number.
