vhost: remove assertion to prevent crash
QEMU will assert on vhost-user backed virtio device hotplug if QEMU is
using more RAM regions than VHOST_MEMORY_MAX_NREGIONS (for example if
it were started with a lot of DIMM devices).
Fix it by returning error instead of asserting and let callers of
vhost_set_mem_table() handle error condition gracefully.
