[PATCH RESEND] spi: spi-uclass: Use unwind goto

[Andrew Goodbody]

In _spi_get_bus_and_cs the check for stacked parallel support needing
multiple chip select support does a direct return on error. Instead it
should set the error code in ret and then use the unwind goto.

This issue was found by Smatch.
