dlm: fix possible call to kfree() for non-initialized pointer
Technically dlm_config_nodes() could return error and keep nodes uninitialized. After that on the fail path of we'll call kfree() for that uninitialized value. The patch is simple - we should just initialize nodes with NULL. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David Teigland <teigland@redhat.com>
