bug#1836: emacs -Q -fn "nonexistent" hangs

[Jason Rumney <jasonr@gnu.org>]

The following change seems to fix the problem for me, but I haven't 
tested daemon mode, since I don't know the circumstances in which there 
was a problem in that case (surely a non-existent font should still 
cause an error in daemon mode, since it will prevent frames from being 
created later).
