According to eMMC specification v5.1 section 6.4.3, we should issue CMD1 repeatedly in the idle state until the eMMC is ready even if the mmc_attach_mmc() calls this function with ocr = 0. Otherwise some eMMC devices seems to enter the inactive mode after mmc_init_card() issued CMD0 when the eMMC device is busy.
