iwlwifi: correct descriptions of advanced ucode errors

ucode errors were redefined in new ucode images and all new errors
were showing as advanced sysasserts which was misleading. new errors
are not sequential so additional lookup table added.  errors do not
overlap so both are used to support older and newer ucode images.
