fix #H4066 - bug eating ring of protection
Intrinsic protection of 0 (usually from having a gremlin steal divine
protection, but also possible by eating a +0 ring of protection) does
not contribute to "magic cancellation", the defense attribute that
makes some special attacks fail. That's intended. Negative intrinsic
protection (not possible from having divine protection, but turns out
to be possible from eating negatively enchanted/charged rings of
protection), did contribute. That wasn't intended, so stop it.
(Positive intrinsic protection gives a magic cancellation of 1 if worn
armor doesn't provide any MC.)
