spi: spi-fsl-dspi: Fix a resource leak in an error handling path
commit 680ec0549a055eb464dce6ffb4bfb736ef87236e upstream
'dspi_request_dma()' should be undone by a 'dspi_release_dma()' call in the
error handling path of the probe function, as already done in the remove
function
Fixes: 90ba37033cb9 ("spi: spi-fsl-dspi: Add DMA support for Vybrid")
