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") Spotted-by: Dan Carpenter <dan.carpenter@oracle.com> Suggested-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Michael S.
