hsr: fix incorrect warning
When HSR interface is setup using ip link command, an annoying warning
appears with the trace as below:-
[ 203.019828] hsr_get_node: Non-HSR frame

As this is an expected path to hsr_get_node() with frame coming from
the master interface, add a check to ensure packet is not from the
master port and then warn.
