As per the C99 standard snprintf() returns the length of the data
that *would have been* written if there were enough space for it.
It's generally considered safer to use the scnprintf() variant.

This patch replaces snprintf() varaint with scnprintf() in
scenario to know the actual length of the data rather than *would
have been* written data of snprintf().
No functional changes intended.
