skbuff: remove unused variable `doff'
There are two instances of an unused variable, `doff' added by commit 6fa01ccd8830 ("skbuff: Add pskb_extract() helper function") in pskb_carve_inside_header() and pskb_carve_inside_nonlinear(). Remove these instances, they are not used. Reported by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Sowmini Varadhan <sowmini.varadhan@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
