[PATCH] cpufreq: schedutil: Replace sprintf() with sysfs_emit() in sysfs show

[Zhongqiu Han]

Use sysfs_emit() instead of sprintf() in rate_limit_us_show().

sysfs_emit() is the preferred API for sysfs output as it provides
PAGE_SIZE bounds checking and ensures proper sysfs formatting.

No functional change intended.
