Fix nptl/tst-cancel-self-cancelstate.c warning.

This patch fixes "../sysdeps/nptl/pthread.h:670:26: warning:
initialization discards 'volatile' qualifier from pointer target type"
arising when building nptl/tst-cancel-self-cancelstate.c.  The problem
is passing a volatile int * to a macro expecting void *; the patch
adds an explicit cast.

Tested for x86_64.

	* nptl/tst-cancel-self-cancelstate.c (do_test): Cast argument of
	pthread_cleanup_push to void *.
