[patch 2/5] MdeModulePkg/BMMUI: Remove the incorrect and useless codes

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

When updating console page, the "ConsoleCheck" in BmmFakeNvData may maintain
the old uncommitted data, we should not copy it to BmmOldFakeNVData.
And in BootMaintRouteConfig function, when save data successfully,
it will copy the BmmFakeNvData to the BmmOldFakeNVData.
So we can delete the logic here.
