[PATCH] dmaengine: stm32-mdma: Add missing check for device_property_read_u32_array

[Markus Elfring]

> Add check for the return value of device_property_read_u32_array() and
> return the error if it fails in order to catch the error.

* Were any source code analysis tools involved here?

* Did anything hinder to add any tags (like “Fixes” and “Cc”) accordingly?
