mmc: usdhi6rol0: fix error return code in usdhi6_probe()

[ Upstream commit 2f9ae69e5267f53e89e296fccee291975a85f0eb ]

Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.

Fixes: 75fa9ea6e3c0 ("mmc: add a driver for the Renesas usdhi6rol0 SD/SDIO host controller")
