[LTP] [PATCH] Disable failure hints before we actually run the test

[Cyril Hrubis]

This is patch based on a suggestion from Peter Vorel:

http://patchwork.ozlabs.org/project/ltp/patch/20240527202858.350200-2-pvorel@suse.cz/

Peter proposed not to print failure hints (the tags) if we fail to
acquire the device. This patch extends it for the whole test library
intialization and enables the failure hints right before we jump into
the test function.
