parisc: led: Use scnprintf() to avoid string truncation warning

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

We intentionally truncate the string and store only up to 20 characters
since the LCD display does not provide more chars. For that use
scnprintf() instead of snprintf() to avoid the warning.
