spapr: Drop dead code in spapr_reallocate_hpt()
Sometimes QEMU needs to allocate the HPT in userspace, namely with TCG
or PR KVM. This is performed with qemu_memalign() because of alignment
requirements. Like glib's allocators, its behaviour is to abort on OOM
instead of returning NULL.
This could be changed to qemu_try_memalign(), but in the specific case
of spapr_reallocate_hpt(), the outcome would be to terminate QEMU anyway
since no HPT means no MMU for the guest. Drop the dead code instead.
