spi/i.MX: fix broken error handling for gpio_request
i.MX35-provided chipselects are represented using negative numbers. If
gpio_request() fails and the previous chipselect was a negative number,
the while loop is endless (i is never decremented).
Also, the error loop would never call gpio_free on chipselect[0].
And finally, the error message was missing an endline.
