mmc: core: Fix voltage select in DDR mode

BugLink: http://bugs.launchpad.net/bugs/922799

commit 913047e9e5787a90696533a9f109552b7694ecc9 upstream.

This patch fixes the wrong comparison before setting the interface
voltage in DDR mode.

The assignment to the variable ddr before comaprison is either
ddr = MMC_1_2V_DDR_MODE; or ddr == MMC_1_8V_DDR_MODE. But the comparison
is done with the extended csd value if ddr == EXT_CSD_CARD_TYPE_DDR_1_2V.
