There are three functions which would invoke the ipvlan_count_rx. They
are ipvlan_process_multicast, ipvlan_rcv_frame, and ipvlan_nf_input.
The former two functions already use the ipvlan directly before
ipvlan_count_rx, and ipvlan_nf_input gets the ipvlan from
ipvl_addr->master, it is not possible to be NULL too.
So the ipvlan pointer check is unnecessary in ipvlan_count_rx.
