Make GetSlotInvalidationCause() return RS_INVAL_NONE on unexpected input

Browse Source 
943f7ae1c8 has changed GetSlotInvalidationCause() so as it would
return the last element of SlotInvalidationCauses[] when an incorrect
conflict reason name is given by a caller, but this should return
RS_INVAL_NONE in such cases, even if such a state should never be
reached in practice.

Per gripe from Peter Smith.
