netfilter: nf_ct_expect: Change __nf_ct_expect_check() return value.
[ Upstream commit 4b86c459c7bee3acaf92f0e2b4c6ac803eaa1a58 ]
Commit 4dee62b1b9b4 ("netfilter: nf_ct_expect: nf_ct_expect_insert()
returns void") inadvertently changed the successful return value of
nf_ct_expect_related_report() from 0 to 1 due to
__nf_ct_expect_check() returning 1 on success. Prevent this
regression in the future by changing the return value of
__nf_ct_expect_check() to 0 on success.
