[PATCH] iio: magnetometer: bmc150_magn: Convert to use sysfs_emit_at() API

[ye.xingchen]

From: ye xingchen <ye.xingchen@xxxxxxxxxx>

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
