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



[ Upstream commit 6052b3c370fb82dec28bcfff6d7ec0da84ac087a ]

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.
