wifi: iwlwifi: mvm: factor out iwl_mvm_sta_fw_id_mask()
We are going to need this in more places than just the key code, so factor out the functionality of getting the FW station ID mask (filtered to a specific link if needed) to a separate function that can now be called both under RCU and mvm->mutex protection.
