gro: Only reset frag0 when skb can be pulled

commit 17dd759c67f21e34f2156abcf415e1f60605a188 upstream.

Currently skb_gro_header_slow unconditionally resets frag0 and
frag0_len.  However, when we can't pull on the skb this leaves
the GRO fields in an inconsistent state.

This patch fixes this by only resetting those fields after the
pskb_may_pull test.
