mmc: core: Reset HPI enabled state during re-init and in case of errors
During a re-initialization of the eMMC card, we may fail to re-enable HPI. In these cases, that isn't properly reflected in the card->ext_csd.hpi_en bit, as it keeps being set. This may cause following attempts to use HPI, even if's not enabled. Let's fix this!
