esp6: fix incorrect null pointer check on xo
The check for xo being null is incorrect, currently it is checking for non-null, it should be checking for null. Detected with CoverityScan, CID#1429349 ("Dereference after null check") Fixes: 7862b4058b9f ("esp: Add gso handlers for esp4 and esp6") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
