wifi: ath9k: simplify ar9003_hw_process_ini()

Browse Source 
Since commit 8896934c16 ("ath9k_hw: remove direct accesses to channel
mode flags") changes 'ar9550_hw_get_modes_txgain_index()' so it never
returns -EINVAL, and 'ar9561_hw_get_modes_txgain_index()' never returns
negative value too, an extra check in 'ar9003_hw_process_ini()' may be
dropped.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
