[PATCH 4.9 13/62] net/qla3xxx: fix potential memleak in ql3xxx_send()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Zhang Changzhong <zhangchangzhong@huawei.com>

[ Upstream commit 62a7311fb96c61d281da9852dbee4712fc8c3277 ]

The ql3xxx_send() returns NETDEV_TX_OK without freeing skb in error
handling case, add dev_kfree_skb_any() to fix it.

Fixes: bd36b0ac5d06 ("qla3xxx: Add support for Qlogic 4032 chip.")
