netfilter: nfnetlink_osf: fix possible bogus match in nf_osf_find()
nf_osf_find() incorrectly returns true on mismatch, this leads to
copying uninitialized memory area in nft_osf which can be used to leak
stale kernel stack data to userspace.
Fixes: 22c7652cdaa8 ("netfilter: nft_osf: Add version option support")
