net: bridge: fix multicast-to-unicast with fraglist GSO
[ Upstream commit 59c878cbcdd80ed39315573b3511d0acfd3501b5 ]
Calling skb_copy on a SKB_GSO_FRAGLIST skb is not valid, since it returns
an invalid linearized skb. This code only needs to change the ethernet
header, so pskb_copy is the right function to call here.
