Tamura Dai 2b4479eb46 spi: spi-imx: Add check for spi_imx_setupxfer() ...

[ Upstream commit 951a04ab3a2db4029debfa48d380ef834b93207e ]

Add check for the return value of spi_imx_setupxfer().
spi_imx->rx and spi_imx->tx function pointer can be NULL when
spi_imx_setupxfer() return error, and make NULL pointer dereference.

 Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
