Subject: [PATCH] Properly update iv_name of disks while changing templates
Trasforming the disk of an instance from DRBD to plain did not properly
update the iv_name of disks, leaving it to None.
This commit modifies _ConvertDrbdToPlain to properly set the iv_name
variables.
An analogous fix is not required in the opposite function,
_ConvertPlainToDrbd, because it uses _GenerateDiskTemplate, that already
takes care of doing that.
Fixes Issue 403.
