Daniel Henrique Barboza 9478956794 hw/ppc/spapr_hcall: set htab_shift after kvmppc_resize_hpt_commit 
Newer kernels have a htab resize capability when adding or remove
memory. At these situations, the guest kernel might reallocate its
htab to a more suitable size based on the resulting memory.

However, we're not setting the new value back into the machine state
when a KVM guest resizes its htab. At first this doesn't seem harmful,
but when migrating or saving the guest state (via virsh managedsave,
for instance) this mismatch between the htab size of QEMU and the
kernel makes the guest hangs when trying to load its state.

Inside h_resize_hpt_commit, the hypercall that commits the hash page
resize changes, let's set spapr->htab_shift to the new value if we're
sure that kvmppc_resize_hpt_commit were successful.

While we're here, add a "not RADIX" sanity check as it is already done
in the related hypercall h_resize_hpt_prepare.
