[LTP] [PATCH v2] lib/safe_file_ops.c: Fix resource leak

Hi Bogdan,

I guess we don't care about closing file descriptor in both safe_file_scanf()
and safe_file_vprintf() because test exits due used tst_brkm_().

And we *do* care in file_printf() with err: label because we don't exit there
(tst_resm_() does not exit).

But instead, you could replace fopen() / fclose() which is followed by
tst_brkm_() by safe_fopen() / safe_fclose() (to shorten the code).

Kind regards,
Petr
