spi: spi-geni-qcom: Print an error when we timeout setting the CS

If we're using geni to manage the chip select line (don't do it--use a
GPIO!) and we happen to get a timeout waiting for the chip select
command to be completed, no errors are printed even though things
might not be in the best shape.  Let's add a print.
