netdev-linux: Rename sturct nedev_linux field as is_lag_primary

Recently OVS adopted a policy of using the inclusive naming word list v1
[1, 2].

This patch partially addresses the use of the term primary 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.
