spapr: Plug minor memory leak in spapr_machine_init()

spapr_machine_init() leaks an Error object when
kvmppc_check_papr_resize_hpt() fails and spapr->resize_hpt is
SPAPR_RESIZE_HPT_DISABLED, i.e. when the host doesn't support hash
page table resizing, and the user didn't ask for it.  As harmless as
memory leaks can possibly be.  Plug it.
