Remove disband ghost unit work around
Remove disband ghost unit work around

The Freeciv server is much better at avoiding ghost units now days.

The ghost unit work around in key_unit_disband() causes problems when the
server refuses to disband the unit. This can happen when the player orders
an undisbandable unit to disband or when disband is blocked by Recycle Unit
or Help Wonder.
