net: team: Track rx enablement separately from tx enablement
Separate the rx and tx enablement/disablement into different
functions so that it is easier to interact with them independently
later.
Although this patch changes receive and transmit paths, the actual
behavior of the teaming driver should remain unchanged, since there
is no option introduced yet to change rx or tx enablement
independently. Those options will be added in follow-up patches.
