Subject: [PATCH 1/2] usb: gadget: f_fs: Use sysfs_emit() in configfs show function

Use sysfs_emit() instead of sprintf() in configfs attribute show function.
sysfs_emit() is the recommended API for sysfs output as it provides buffer
overflow protection and proper formatting.

No functional changes.
