dlm: reject messages from non-members
Messages from nodes that are no longer members of the lockspace should be ignored. When nodes are removed from the lockspace, recovery can sometimes complete quickly enough that messages arrive from a removed node after recovery has completed. When processed, these messages would often cause an error message, and could in some cases change some state, causing problems. Signed-off-by: David Teigland <teigland@redhat.com>
