spi: imx: Fix freeing of DMA channels if spi_bitbang_start() fails
If the SPI controller has has_dmamode = true and spi_bitbang_start() fails
in spi_imx_probe(), then the driver must release the DMA channels acquired
in spi_imx_sdma_init() by calling spi_imx_sdma_exit() in the fail path.
Fixes: f62caccd12c1 ("spi: spi-imx: add DMA support")
