[PATCH] spi_imx.c: correct the test on platform_get_irq() return value

[Richard Genoud]

The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but the return value of platform_get_irq().
As platform_get_irq() can return an error (-ENXIO) or the IRQ value it found, the test should be "if (spi_imx->irq < 0)"
