The ECMA-167 standard (3rd Edition, June 1997) reserves values 4 through 7 in the ICB.Flags[2:0] bit-field for future standardization; see "14.6 ICB Tag" / "14.6.8 Flags (RBP 18)". https://www.ecma-international.org/publications/standards/Ecma-167.htm The switch (RecordingFlags) statement in the ReadFile() function handles all the standard values, using the constants of the UDF_FE_RECORDING_FLAGS enum type. However, the reserved values are not caught with a "default" case label, which both breaks the edk2 Coding Style Spec, and leaves the Status variable un-initialized, before we return Status under the Done label. Set Status to EFI_UNSUPPORTED if we encounter a reserved value. This issue was reported by Ard's and Gerd's CI systems independently (through build failures with GCC48/GCC49, DEBUG/RELEASE targets).
