[ath5k] Add missing AR5K_EEPROM_READ in ath5k_eeprom_read_turbo_modes

The GCC11 compiler pointed out something that apparently no previous
compiler noticed: in ath5k_eeprom_pread_turbo_modes, local variable
val is used uninitialized. From what I can see, the code is just
missing an initial AR5K_EEPROM_READ. Add it right before the switch
statement.
