perf tests bp_account: Fix build with clang-6
To shut up this compiler warning:
CC /tmp/build/perf/tests/bp_account.o
CC /tmp/build/perf/tests/task-exit.o
CC /tmp/build/perf/tests/sw-clock.o
tests/bp_account.c:106:20: error: pointer type mismatch ('int (*)(void)' and 'void *') [-Werror,-Wpointer-type-mismatch]
void *addr = is_x ? test_function : (void *) &the_var;
^ ~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~1 error generated.
Noticed with clang 6 on fedora rawhide.
