[LTP] [PATCH] lib: Print failure hints only once to reduce log duplication

[Li Wang]

The LTP test currently prints failure hints multiple times if a test
encounters several TFAIL or TBROK results. This leads to unnecessarily
verbose and duplicated logs.

This patch modifies the `print_failure_hints()` function to ensure that
failure hints are printed only once per test run. By setting `show_failure_hints`
to 0 after the first print, subsequent calls to `print_failure_hints()`
will not produce redundant output.

Fixes: 701212f08 ("Disable failure hints before we actually run the test")
