afs: Use a dynamic port if 7001 is in use
It is not required that the afs client operate on port 7001. The port could be in use because another kernel or userspace client has already bound to it. If the port is in use, just fallback to using a dynamic port. Signed-off-by: Marc Dionne <marc.dionne@auristor.com> Signed-off-by: David Howells <dhowells@redhat.com>
