benet: fix return value check in be_lancer_xmit_workarounds()
[ Upstream commit 5c85f7065718a949902b238a6abd8fc907c5d3e0 ]
in be_lancer_xmit_workarounds(), it should go to label 'tx_drop'
if an unexpected value is returned by pskb_trim().
Fixes: 93040ae5cc8d ("be2net: Fix to trim skb for padded vlan packets to workaround an ASIC Bug")
