RSS hash types are encoded values, not independent flags. The bitmask
check in M_HASHTYPE_ISHASH_TCP() also accepts UDP, address-only and opaque
hash types, causing the syncache to retain them instead of falling back
to a software TCP hash.
Compare against the three TCP four-tuple hash types after masking the
inner-header flag. Keep the existing macro interface and use an inline
helper to preserve single evaluation of its argument.
Add ATF coverage for all 256 hash-type byte values, including inner-header
hashes, and verify single evaluation of the mbuf argument.
