[TIPC]: Use tipc_port_unlock

The file net/tipc/port.c takes a lock using the function tipc_port_lock and
then releases the lock sometimes using tipc_port_unlock and sometimes using
spin_unlock_bh(p_ptr->publ.lock).  tipc_port_unlock simply does the
spin_unlock_bh, but it seems cleaner to use it everywhere.

The problem was fixed using the following semantic patch.

+  tipc_port_unlock(p_ptr);
