Uff, the tst_sysfs_attr_exists() does work with printf-like parameters.

What do we need the this wrapper for?

What about we add the counter into the sysfs library instead?

If we add:

void tst_sysfs_cnt_reset(void);

unsigned int tst_sysfs_cnt_get(void);

We can call the tst_sysfs_cnt_rest() at the start of the test function,
and get the counter at the end.
