Peter Rajnoha 00b610e542 filters: do not print [none:nil] as external device info's [source:handler] if "none" source is used
Print [source:handler] in filters' debug messages only if external
device info source other than "none" is used.

$ lvmconfig --type full devices/external_device_info_source
external_device_info_source="none
