[Staging/Bug_1525_FmpDevicePkg_MultipleControllers][PATCH] MdeModulePkg/EsrtFmpDxe: Correct the LastAttemptVersion algorithm in ESRT entry

["Eric Jin" <eric.jin@intel.com>]

Fix the 1nd issue mentioned in https://bugzilla.tianocore.org/show_bug.cgi?id=1525

Update the ESRT entry with the last attempt status and last attempt
version from the first FMP instance whose last attempt status is not
SUCCESS. If all FMP instances are SUCCESS, then set last attempt version
to the smallest value from all FMP instances
