Subject: [PATCH] efi: use EFI_LOADER_(CODE|DATA) for kernel and initrd
 allocations

At some point due to an erroneous kernel warning, we switched kernel and
initramfs to being loaded in EFI_RUNTIME_SERVICES_CODE and
EFI_RUNTIME_SERVICES_DATA memory pools.  This doesn't appear to be
correct according to the spec, and that kernel warning has gone away.

This patch puts them back in EFI_LOADER_CODE and EFI_LOADER_DATA
allocations, respectively.

Resolves: rhbz#2108456
