[PATCH 4/7] x86: events: Convert snprintf() to scnprintf()

[PATCH 4/7] x86: events: Convert snprintf() to scnprintf()

[Jules Irenge]

Coccinnelle reports a warning
Warning: Use scnprintf or sprintf
Adding to that, there has been a slow migration from snprintf to scnprintf.
This LWN article explains the rationale for this change
https: //lwn.net/Articles/69419/
Ie. snprintf() returns what *would* be the resulting length,
while scnprintf() returns the actual length.
