[PATCH 1/3] fix conditional context test case with void

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

The test file for context checking contains a few test cases
with a conditional, mimicking kernels's __cond_lock().
But the macro involved use as condition the return value of
a function, _ca(), which itself returns void ...

Fix the test by giving _ca() a return type of 'int'.
