So even if this doesn't fix anything, I'm fine with this change to prevent more sloppy updates on this code.

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.
