Two small fixes to enable the use soft-reserved/special-purpose memory
(EFI_MEMORY_SP) with dax_kmem on RISC-V (and ARM64, I think, though I
don't have a platform to test it on).
Patch 1 fixes a trivial integer narrowing bug. Patch 2 prevents adding
memblocks for soft-reserved memory so that it can later be hotplugged by
dax_kmem.
Tested on a RISC-V platform that presents a range of EFI_MEMORY_SP with
Bjorn's MEMORY_HOTPLUG series[0] applied.

v1->v2: address comments from Ard
Andrew Bresticker (2):
efi: runtime: Fix potential overflow of soft-reserved region size
efi: Don't add memblocks for soft-reserved memory
Thanks, I'll take these both as fixes.

Thanks!
