cryptsetup: fix flags check

Browse Source 
FLAGS_SET() checks if *all* the bits are set. In this case we want to check
if *any* are. FLAGS_SET() was added in cde2f8605e,
but not a bug then yet, because with just one bit, both options are equivalent.
But when more bits were added later, this stopped being correct.
