ath9k_hw: fix uninitialized variable data

Currently, data variable in ar9003_hw_thermo_cal_apply() could be
uninitialized if ar9300_otp_read_word() will fail to read the value.
Initialize data variable with 0 to prevent an undefined behavior. This
will be enough to handle error case when ar9300_otp_read_word() fails.
