CARD: Avoid potential truncation warnings when allocating the deck buffer

Browse Source 
Card decks will never be excessively large (> uint32) since there never
was a computer room big enough to hold that many cards. :-)

Hopper counts and size are all of type t_addr since they are referenced
relative to uptr->pos which tracks the hopper position.  That state is
managed so position is properly managed across a SAVE/RESTORE.

On some systems that use sim_card, t_addr is 64bits, hence
