[LTP] [PATCH 2/2] swapon01: Simplify code, add copyright

[Petr Vorel]

Remove  ambiguous comment with -i option during swapoff,
it's needed for a test cleanup anyway.

Signed-off-by: Petr Vorel <pvorel@suse.cz>

I wonder which command's -i option is meant. runltp -i ? swapon does not
have -i option.

Kind regards,
Petr
