ax25: Fix segfault after sock connection timeout [ Upstream commit 8a367e74c0120ef68c8c70d5a025648c96626dff ] The ax.25 socket connection timed out & the sock struct has been previously taken down ie. sock struct is now a NULL pointer. Checking the sock_flag causes the segfault. Check if the socket struct pointer is NULL before checking sock_flag. This segfault is seen in timed out netrom connections. Please submit to -stable.
