[PATCH] When building the exceptionDisks list, skip devices libparted doesn't like.

[Chris Lumens <clumens redhat com>]

libparted does not probe for a lot of devices, notably things like /dev/sr0.
There's no real way to handle this in pyparted since we can't distinguish a
valid but unprobeable device from an invalid device at that layer.  So,
anaconda needs to skip anything libparted refuses to probe.
