LoongArch: Replace sprintf() with sysfs_emit()

Tao Cui · chenhuacai · commit d6d69f0edde6 · 2025-09-18T19:44:04.000+08:00
As Documentation/filesystems/sysfs.rst suggested, show() should only use
sysfs_emit() or sysfs_emit_at() when formatting the value to be returned
to user space.

No functional change intended.
