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.")
