ASoC: stm32: sai: fix device leak on probe

commit e26ff429eaf10c4ef1bc3dabd9bf27eb54b7e1f4 upstream.

Make sure to drop the reference taken when looking up the sync provider
device and its driver data during DAI probe on probe failures and on
unbind.

Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.

Fixes: 1c3816a19487 ("ASoC: stm32: sai: add missing put_device()")
