mmc: usdhi6rol0: Fix a resource leak in the error handling path of the probe

Browse source 
[ Upstream commit 6052b3c370 ]

A call to 'ausdhi6_dma_release()' to undo a previous call to
'usdhi6_dma_request()' is missing in the error handling path of the probe
function.

It is already present in the remove function.

Fixes: 75fa9ea6e3 ("mmc: add a driver for the Renesas usdhi6rol0 SD/SDIO host controller")
