["Dandan Bi" <dandan.bi@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2326

Currently when meet mismatch case for one-of and ordered-list
menu, just show a popup window to indicate mismatch, no more
info for debugging. This patch is to add more debug message
about mismatch menu info which is helpful to debug.
