doc: fix disk=0 use case in flavor doc

Browse Source 
The 0 value of the disk parameter of the flavor is only meaningfull
if the instance is booted from volume as in any other case the
instance will use local disk and the scheduler will not be
able to select the hosts based on the real image size as that
information is not available for the scheduler.
