32 Internal worker function that reports a status code through the Status Code Protocol
34 This function checks to see if a Status Code Protocol is present in the handle
35 database. If a Status Code Protocol is not present, then EFI_UNSUPPORTED is
36 returned. If a Status Code Protocol is present, then it is cached in gStatusCode,
37 and the ReportStatusCode() service of the Status Code Protocol is called passing in
38 Type, Value, Instance, CallerId, and Data. The result of this call is returned.
