[libvirt] [PATCH 0/2] Change virFileIsCDROM to check cdrom status

Refactor virFileIsCDROM to virFileCheckCDROM and now it could be used to store cdrom status. In libvirt, it gives general Input/Output error when reading a not ready cdrom backend vol. This error should be replaced with warning just like the warning of lacking backing file.
