[PATCH 1/2] mci: sdhci: propagate tuning failures from sdhci_execute_tuning()

[Sascha Hauer <s.hauer@pengutronix.de>]

From: Sascha Hauer <sascha@saschahauer.de>

sdhci->tuning_err is set but never used. Drop it and return the tuning
error directly from sdhci_execute_tuning(). With this we can actually
return tuning errors instead of silently ignoring them.
