scsi: zfcp: implicitly refresh config-data diagnostics when reading sysfs
Adds implicit updates of cached diagnostics via Exchange Config Data when
reading sysfs attributes interfacing them. Right now this only affects the
new B2B-Credit diagnostic attribute.
This uses the same mechanism previously also used for cached diagnostics
of Exchange Port Data.
