raid: do not enforce flushing of raids when it is not required

Browse Source 
This is probably somewhat experimantal patch - but when i.e. raid device
is just extend, there should not be a technical need for flush,
unless the target would stricly need it.  It should allow faster
processing of lvm command not being blocked by possibly longer flush.
