System Memory map is changed when a memory range is Accepted.
While returning from AcceptAllMemory(), "gBS->FreePool" is wrongly
used which results in changing memory map and hence return an error.
Fix this by removing the "gBs->FreePool" call altogether.
Before this patch, KVM guest throws an error and control goes to the
boat loader menu every time we select an OS:
EFI stub: ERROR: exit_boot() failed!
EFI stub: ERROR: efi_main() failed!
StartImage failed: Invalid Parameter
