[PATCH 3/3] perf/x86/amd:Convert snprintf() to sysfs_emit()

[Jules Irenge]

Coccinelle reports a warning
WARNING: use scnprintf or sprintf

Following the advice on kernel documentation
https://www.kernel.org/doc/html/latest/filesystems/sysfs.html

For show(device *...) functions, only use sysfs_emit() or sysfs_emit_at()
especially when formatting the value to be returned to user space.
Convert snprintf() to sysfs_emit()
