subs: Simplify checks whether a ship just read exists

Browse source 
Ships with efficiency below the minimum have their owner set to zero
on write to the ship file.  Therefore, a ship just read from the ship
file exists unless its owner is zero.  Additionally checking
efficiency is redundant.  Same for planes and land units.  Drop
obviously redundant efficiency checks.
