Stop throwing when the invalid capability is passed

Browse source 
When new capability is introduced and added to capaility or
forbiddenCapability by default, module rollback could cause system
server crash since JobScheduler persists network request that contains
new capability that is invalid for old code.
This CL updates capability validation not to throw exception to avoid
system crash in this case.
