pasemi_mac: A couple of minor bugfixes.
Bugfixes: * Move the wake_queue logic from tx_intr to clean_tx * Always do wake_queue even if queue wasn't full before clean since it's safe to do * Fix polarity in checks in pasemi_mac_close Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
