ath9k: check pdata variable before dereferencing it
Due to my recent commit (ath9k: allow to load EEPROM content via firmware API) smatch complains about that the 'pdata' variable in 'ath9k_hw_init' can be NULL and it is dereferenced before checking that. That is absolutely correct. Check the 'pdata' variable before using it to avoid a NULL pointer dereference.
