bareudp: Fix invalid read beyond skb's linear data
Data beyond the UDP header might not be part of the skb's linear data.
Use skb_copy_bits() instead of direct access to skb->data+X, so that
we read the correct bytes even on a fragmented skb.
Fixes: 4b5f67232d95 ("net: Special handling for IP & MPLS.")
