ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP

[ Upstream commit b13a3e5fd40b7d1b394c5ecbb5eb301a4c38e7b2 ]

When a platform marks a memory range as "special purpose" it is not
onlined as System RAM by default. However, it is still suitable for
error injection. Add IORES_DESC_SOFT_RESERVED to einj_error_inject() as
a permissible memory type in the sanity checking of the arguments to
_EINJ.
