efi/arm64: Fix kmemleak false positive in arm64_efi_rt_init()
The kmemleak code sometimes complains about the following leak:
unreferenced object 0xffff8000102e0000 (size 32768):
comm "swapper/0", pid 1, jiffies 4294937323 (age 71.240s)
hex dump (first 32 bytes):
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
backtrace:

The memory object in this case is for efi_rt_stack_top and is allocated
in an initcall. So this is certainly a false positive. Mark the object
as not a leak to quash it.
