Fix crash in xf86InitOrigins()

Browse source 
In a multihead setup, if only the first screen can be
initialized, but the second screen is mentioned first in the
ServerLayout section, the xf86InitOrigins() function will crash
because the screen referred to in the e.g. "RightOf" part is
non-existent.
