iio: sw-device: Fix config group initialization

Use the IS_ENABLED() helper macro to ensure that the configfs group is
initialized either when configfs is built-in or when configfs is built as a
module. Otherwise software device creation will result in undefined
behaviour when configfs is built as a module since the configfs group for
the device not properly initialized.

Similar to commit b2f0c096 ("iio: sw-trigger: Fix config group
initialization").
