spi: atmel-quadspi: Fix printed error code during DMA setup
On dma_request_chan() failure driver NULL-ifies the 'rx_chan' and
immediately uses it as PTR_ERR() so dev_err_probe() prints incorrect
error code. Rework the code so proper error code will be printed and
NULL-ifying of 'rx_chan' will happen in common error handling block
(failure of DMA setup is not fatal for the driver and further code
depends on 'rx_chan' being non-NULL for DMA operations).
Reported by Smatch:
drivers/spi/atmel-quadspi.c:1287 atmel_qspi_dma_init() warn: passing zero to 'PTR_ERR'
