datapath: Fix deadlock in switch port removal.

dp_del_switch_port() cancels the port_task and waits for
it to finish, but the port_task requires the RTNL lock
to complete, which dp_del_switch_port() holds, thus a
deadlock.

This commit fixes the problem, by deleting the port_task
entirely and moving its work into secchan.
