Subject: [PATCH 2/3] Lockd: don't mark freshly created sockets with XPT_CHNGBUF

This is a cleanup patch. XPT_CHNGBUF bit is set on UDP socket creation. Calling
svc_sock_update_bufs from lockd after is redundant.
Below is Lockd UDP sockets creating call trace:

lockd_up {

make_socks
create_lockd_family
create_lockd_listener
svc_create_xprt
__svc_xpo_create
svc_udp_create
svc_create_socket
svc_setup_socket
svc_udp_init (raise XPT_CHNGBUF)

....

svc_sock_update_bufs (raise XPT_CHNGBUF again)

....

}
