mmc: sdhci-cadence: Fix an error handling path in sdhci_cdns_probe()
If devm_reset_control_get_optional_exclusive() fails, some resources still
need to be released. So branch to the error handling path instead of
returning directly.
Fixes: aad53d4ee756 ("mmc: sdhci-cadence: Support mmc hardware reset")
