[PATCH V3] efi/libstub/x86: Avoid EFI map buffer alloc in allocate_e820()

In allocate_e820(), call the EFI get_memory_map() service directly instead of indirectly via efi_get_memory_map(). This avoids allocation of a buffer and return of the full EFI memory map, which is not needed here and would otherwise need to be freed. Routine allocate_e820() only needs to know
