[PATCH 07/10] zfcp: implicitly refresh port-data diagnostics when reading SysFS

This patch adds implicit updates to the SysFS entries that read the diagnostic data stored in the "caching buffer" for Exchange Port Data. An update is triggered once the buffer is older than ZFCP_DIAG_MAX_AGE milliseconds (5s). This entails sending an Exchange Port Data command to the FCP-Channel
