spi: spi-geni-qcom: correctly handle -EPROBE_DEFER from dma_request_chan()
[ Upstream commit 9d7054fb3ac2e8d252aae1268f20623f244e644f ]
Now spi_geni_grab_gpi_chan() errors are correctly reported, the
-EPROBE_DEFER error should be returned from probe in case the
GPI dma driver is built as module and/or not probed yet.
Fixes: b59c122484ec ("spi: spi-geni-qcom: Add support for GPI dma")
Fixes: 6532582c353f ("spi: spi-geni-qcom: fix error handling in spi_geni_grab_gpi_chan()")
