ASoC: codecs: wcd937x: Fix error handling in wcd937x codec driver

In wcd937x_bind(), the driver calls of_sdw_find_device_by_node() to
obtain references to RX and TX SoundWire devices, which increment the
device reference counts. However, the corresponding put_device() are
missing in both the error paths and the normal unbind path in
wcd937x_unbind().

Add proper error handling with put_device() calls in all error paths
of wcd937x_bind() and ensure devices are released in wcd937x_unbind().
