Fix marking of unused trade slots

Trade code can't quite decide whether negative trd_unitid or zero
trd_owner marks unused slots.  The former is a bad idea, because blank
slots have a zero trd_unitid.

Make sure to zero trd_owner when setting trd_unitid to negative value
in trad() and check_trade().  This fixes recognition of unused slots
in set (broken in commit e16e38df, v4.2.18) and xdump (never worked).
