QEMU will crashes with
qapi/qobject-output-visitor.c:210: qobject_output_complete: Assertion `qov->root && ((&qov->stack)->slh_first == ((void *)0))' failed
when trying to get value of not set hostmem's "host-nodes"
property, HostMemoryBackend::host_nodes bitmap doesn't have
any bits set in it, which leads to find_first_bit() returning
MAX_NODES and consequently to an early return from
host_memory_backend_get_host_nodes() without calling visitor.
Fix it by calling visitor even if "host-nodes" property wasn't
set before exiting from property getter to return valid empty
list.
