[PATCH] mmc: tmio: Use common error handling code in tmio_mmc_host_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 27 Oct 2017 19:09:17 +0200

* Add a jump target so that a bit of exception handling can be better
  reused at the end of this function.

* Adjust condition checks.

This issue was detected by using the Coccinelle software.
