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.
