[PATCH 4.19 318/321] ASoC: stm32: sai: add missing put_device()

From: Wen Yang <yellowriver2010@hotmail.com>

commit 1c3816a194870e7a6622345dab7fb56c7d708613 upstream.

The of_find_device_by_node() takes a reference to the underlying device
structure, we should release that reference.

Fixes: 7dd0d835582f ("ASoC: stm32: sai: simplify sync modes management")
