ASoC: stm32: sai: Add missing cleanup

Browse source 
[ Upstream commit 7506baeed8d05fc164254c64af14cfed2ac14446 ]

The commit 0d6defc7e0e4 ("ASoC: stm32: sai: manage rebind issue")
converts some function calls to their non-devm equivalents.  The
appropriate cleanup code was added to the remove function, but not
to the probe function.  Add a call to snd_dmaengine_pcm_unregister
to compensate for the call to snd_dmaengine_pcm_register in case
of subsequent failure.

Fixes: commit 0d6defc7e0e4 ("ASoC: stm32: sai: manage rebind issue")
