The main loop in __ice_clean_ctrlq first checks if a VF might be malicious before calling ice_vc_process_vf_msg(). This results in duplicate code in both functions to obtain a reference to the VF, and exports the ice_is_malicious_vf() from ice_virtchnl.c unnecessarily. Refactor ice_is_malicious_vf() to be a static function that takes a pointer to the VF. Call this in ice_vc_process_vf_msg() just after we obtain a reference to the VF by calling ice_get_vf_by_id. Pass the mailbox data from the __ice_clean_ctrlq function into ice_vc_process_vf_msg() instead of calling ice_is_malicious_vf(). This reduces the number of exported functions and avoids the need to obtain the VF reference twice for every mailbox message. Note that the state check for ICE_VF_STATE_DIS is kept in ice_is_malicious_vf() and we call this before checking that state in ice_vc_process_vf_msg. This is intentional, as we stop responding to VF messages from a VF once we detect that it may be overflowing the mailbox. This ensures that we continue to silently ignore the message as before without responding via ice_vc_send_msg_to_vf().
