xl: Perform minimal validation of virtual disk file while parsing config file

This patch performs some very basic validation on the virtual disk
file passed through the config file. This validation ensures that we
don't go too far with the initialization like spawn qemu and more
while there could be some potentially fundamental issues.

[ Patch fixed up to work with PHYSTYPE_EMPTY 22808:6ec61438713a -iwj ]
