[PATCH] mmc-core: One check less in mmc_select_hs200() after error detection

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 29 Dec 2015 20:28:46 +0100

This issue was detected by using the Coccinelle software.

Move the jump label directly before the desired log statement
so that the variable "err" will not be checked once more
after it was determined that a call of the function
"__mmc_set_signal_voltage" or "__mmc_switch" failed.
Use the identifier "report_failure" instead of the label "err".
