[stp] Fix incorrectly disambiguated errors

The three nominally-disambiguated ENOTSUP errors accidentally all used
the same error disambiguator, rendering them identical.  Fix by
changing all three values.  We avoid reusing the 0x01 disambiguator
value, since that remains ambiguous in older binaries.
