net: team: Annotate reads and writes for mixed lock accessed values

Browse source

The team_port's "index" and the team's "en_port_count" are read in
the hot transmit path, but are only written to when holding the rtnl
lock.

Use READ_ONCE() for all lockless reads of these values, and use
WRITE_ONCE() for all writes.
