SYSLINK: ipc - fixes in messageq and nameserver_remotenotify

This patch fixes the issues found in..
	-messageq.c: messageq_open() now returns standard Linux
		error -NOENT instead of MESSAGEQ_E_NOTFOUND.
	-nameserver_remotenotify.c: nameserver_remotenotify_get()
		calls  gatepeterson_leave() in the case of failure.
