[PATCH] net: x25: remove null checks on arrays calling_ae and called_ae

From: Colin Ian King <redacted>

dtefacs.calling_ae and called_ae are both 20 element __u8 arrays and
cannot be null and hence are redundant checks. Remove these.

Indeed, and if they were pointers they would be in userspace and would
need proper uaccess handling.

Applied to net-next, thanks.
