Don't prune 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 5150b45fd355
("net: hsr: Fix node prune function for forget time expiry") this issue
is fixed unvealing the issue described above.
