iwlagn: simplify error table reading
The current code to read the error table header
just hardcodes all the offsets, which is a bit
hard to understand. We can read in the entire
header (as much as we need) into a structure,
and then take the data from there, which makes
it easier to understand. To read a bigger blob
we also don't need to grab NIC access for each
word read, making the code more efficient.
