dev_manager: no flush for extension

Browse Source 
Recognize the target only 'extends' and do not enforce
'flush' in this case.  Only the size reduction
still requires flush (so disables usage of no_flush flag).

If some other targets do require flush before suspend,
they have to explicitly ask for it.
