[PATCH net] tcp: Export tcp_write_queue_purge()

[Florian Fainelli]

After tcp_write_queue_purge() got uninlined with commit ac3f09ba3e49
("tcp: uninline tcp_write_queue_purge()"), it became no longer possible
to reference this symbol from kernel modules.

Fixes: ac3f09ba3e49 ("tcp: uninline tcp_write_queue_purge()")
