spi: spi-fsl-dspi: Fix a resource leak in an error handling path

Browse Source 
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: 90ba37033c ("spi: spi-fsl-dspi: Add DMA support for Vybrid")
