Subject: [PATCH] edac: Use sysfs_emit_at() in dimmdev_location_show()

Replace the use of scnprintf() with sysfs_emit_at() in
dimmdev_location_show() to format the output into the sysfs buffer.

This change improves clarity and ensures proper bounds checking in
line with the preferred sysfs_emit() API usage for sysfs 'show'
functions. The PAGE_SIZE check is now handled internally by the helper.

No functional change intended.
