Subject: When MF_HARD_RESET monsters die/reset/etc, destroy the items they
 hold so they don't hang around cluttering up mitm[]

Don't set the values of a cell from mitm[] unless it's sure to be used; using
it as a scratch object or partially setting it up and then bailing clutters up
mitm[] with valid but unused items, preventing those slots from being used.
