[PATCH REBASE 3/4] vz: fix boot check to use new disk id

[Nikolay Shirokovskiy <nshirokovskiy@xxxxxxxxxxxxx>]

Current implementation does not detects all incompatible configurations.
For example if we have in vzsdk bootorder "cdrom1, cdrom0" (that is
"hdb, hda" in case of ide cdroms) and cdroms do not have disk
images inserted. In this case boot order check code fail to
distiguish them at all as for both PrlVmDev_GetFriendlyName gives "".
Well the consequences are only missing warnings but as
we just have introduced all the necessary tools to face the problem -
let's fix it.
