[Xcb] [PATCH xpyb 04/10] except.c: Delete explicit comparison with NULL

[Tapasweni Pathak]

if (pointer == NULL) is functionally equivalent to
if (!pointer).

Using the second will make it a bit obvious that there is a
pointer involved and not an integer or something.

This patch deletes explicit comaprison with NULL in except.c file.
