conf: Change when virDomainDiskDefAssignAddress is called

Rather than calling virDomainDiskDefAssignAddress during the parsing of
the XML, moving the setting of disk addresses into the domain/device post
processing.

Commit id '37588b25' which introduced VIR_DOMAIN_DEF_PARSE_DISK_SOURCE
in order to avoid generating the address which wasn't required will not
be affected by this as all it cared about was processing the source XML.
