Recently OVS adopted a policy of using the inclusive naming word list v1
[1, 2].
This patch partially addresses the use of the term master in the
context of LAG devices by using the term primary instead: the
is_lag_master field of struct netdev_linux is renamed is_lag_primary.
A related comment is also updated.
No functional change intended.
