[PATCH v2 3/3] iio: gyro: adis16136: fix unprotected debugfs reads

The serial_number file operations are open coded and never call
debugfs_file_get(), which debugfs_create_file_unsafe() requires.
debugfs_remove_recursive() therefore does not wait for a read in
progress, and unbind frees the iio_dev underneath it.
Use debugfs_create_file() instead.
