tests: fix bad-buffer-test

Browse source 
bad-buffer-test is FAIL_TEST and every assert() (or even SIGSEGV signal)
make it pass. It shouldn't be so for example when assert() is invoked
when a client couldn't connect to display.

Make sure that only relevant asserts make the test pass
and the other make it fail (by returning 0)
