ath9k_hw: Fix EEPROM uncompress block reading on AR9003

commit 803288e61e346ba367373bc7d5eeb6e11c81a33c upstream.

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.
