efi_loader: fix memory type for memory reservation block
The (yet unreleased version of the) devicetree specification clearly
states that:
As with the /reserved-memory node, when booting via UEFI
entries in the Memory Reservation Block must also be listed
in the system memory map obtained via the GetMemoryMap() toi
protect against allocations by UEFI applications. The memory
reservation block entries should be listed with type
EfiReservedMemoryType.
This restores the behaviour that was changed by commit 4cbb2930bd8c
("efi_loader: consider no-map property of reserved memory").
Fixes: 4cbb2930bd8c ("efi_loader: consider no-map property of reserved memory")
