Andreas Oetken d2daa127ed hsr: fix don't prune the master node from the node_db 
Don't prune the master node in the hsr_prune_nodes function.
Neither time_in[HSR_PT_SLAVE_A] nor time_in[HSR_PT_SLAVE_B]
will ever be updated by hsr_register_frame_in for the master port.
Thus, the master node will be repeatedly pruned leading to
repeated packet loss.
This bug never appeared because the hsr_prune_nodes function
was only called once. Since commit 5150b45fd3
("net: hsr: Fix node prune function for forget time expiry") this issue
is fixed unveiling the issue described above.
