e100: Fix possible use after free in e100_xmit_prepare

CVE-2022-49026

Description

In the Linux kernel, the following vulnerability has been resolved:

In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will resend the skb. But the skb is already freed, which will cause UAF bug when the upper layer resends the skb.

Remove the harmful free.
