util: storage: Allow passing <source> also for managed PR case

Browse Source 
To allow storing status information in the XML move the validation that
the 'path' is not valid for managed PR daemon case into
qemuDomainValidateStorageSource and allow parsing of the data even in
case when managed='yes'.
