netpoll: export carrier_timeout via netpoll_get_carrier_timeout()

Browse source

netpoll_wait_carrier() is only used in netconsole, and it will move to
netconsole.

The carrier_timeout module parameter has to stay in netpoll so the
existing netpoll.carrier_timeout kernel parameter keeps working for
current users, and we don't break user compatibility.

Add a netpoll_get_carrier_timeout() accessor and export it so netconsole
can read the value once the carrier wait lives there. Drop the now
redundant timeout argument from netpoll_wait_carrier() (its only caller
passed carrier_timeout) and read the parameter directly while the helper
still lives here.
