fix FPE in libfb

The radeon driver under strange situations when plugging/unplugging an external display can call fbScreenInit with 0 dpi, leading to an FPE.

stack:
 miScreenInit ()
 fbFinishScreenInit () from /usr/lib/xorg/modules//libfb.so
 fbScreenInit () from /usr/lib/xorg/modules//libfb.so
 ?? () from /usr/lib/xorg/modules/drivers//radeon_drv.so
 AddScreen ()

Attached is a patch to fix the FPE.
