Subject: forcedeth: fix tx limit2 flag check

From: Ayaz Abdulla <aabdulla@nvidia.com>

commit 5c659322a904a7cc0265e7b183372b9bdebec6db upstream.

This is a fix for bug 572201 @ bugs.debian.org

This patch fixes the TX_LIMIT feature flag. The previous logic check
for TX_LIMIT2 also took into account a device that only had TX_LIMIT
set.
