Johan Hovold a7e8f3efd5 spi: qup: fix error pointer deref after DMA setup failure 
The driver falls back to PIO mode if DMA setup fails during probe.

Make sure to the clear the DMA channel pointers on setup failure to
avoid dereferencing an error pointer (or attempting to release a channel
a second time) on later probe errors or driver unbind.

This issue was flagged by Sashiko when reviewing a devres allocation
conversion patch.

Fixes: 612762e82a ("spi: qup: Add DMA capabilities")
