xfrm: Fix return value check of copy_sec_ctx.
A recent commit added an output_mark. When copying this output_mark, the return value of copy_sec_ctx is overwitten without a check. Fix this by copying the output_mark before the security context. Fixes: 077fbac405bf ("net: xfrm: support setting an output mark.") Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
