ice: pass mbxdata to ice_is_malicious_vf()
The ice_is_malicious_vf() function takes information about the current state of the mailbox during a single interrupt. This information includes the number of messages processed so far, as well as the number of pending messages not yet processed. A future refactor is going to make ice_vc_process_vf_msg() call ice_is_malicious_vf() instead of having it called separately in ice_main.c This change will require passing all the necessary arguments into ice_vc_process_vf_msg(). To make this simpler, have the main loop fill in the struct ice_mbx_data and pass that rather than passing in the num_msg_proc and num_msg_pending.
