MdeModulePkg: Upon BootOption failure, Destroy RamDisk memory before RSC.
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2818
For better memory management, re-ordered the DestroyRamDisk and
ReportStatusCode calls inside the EfiBootManagerBoot() function.
This will help to clean the unused memory before reporting the
failure status, so that OEMs can use RSC Listener to launch
custom boot option or application for recovering the failed
hard drive.
This change will help to ensure that the allocated pool of memory
for the failed boot option is freed before executing OEM's RSC
listener callback to handle every boot option failure.
