vhost: fix error handling for memory region alloc

callers of vhost_kvzalloc() expect the same behaviour on
allocation error as from kmalloc/vmalloc i.e. NULL return
value. So just return vzmalloc() returned value instead of
returning ERR_PTR(-ENOMEM)

Fixes: 4de7255f7d2be5 ("vhost: extend memory regions allocation to vmalloc")
