efi: libstub: drop pointless get_memory_map() call
commit d80ca810f096ff66f451e7a3ed2f0cd9ef1ff519 upstream.
Currently, the non-x86 stub code calls get_memory_map() redundantly,
given that the data it returns is never used anywhere. So drop the call.
Cc: <stable@vger.kernel.org> # v4.14+
Fixes: 24d7c494ce46 ("efi/arm-stub: Round up FDT allocation to mapping size")
