ath9k_hw: Fix EEPROM uncompress block reading on AR9003

The EEPROM is compressed on AR9003, upon decompression
the wrong upper limit was being used for the block which
prevented the 5 GHz CTL indexes from being used, which are
stored towards the end of the EEPROM block. This fix allows
the actual intended regulatory limits to be used on AR9003
hardware.
