This reverts commit 17ea3c862865c0d704646f67dbf8412f9ff54f59.
In eMMC specification, for the response-with-busy(R1b, R5b) command, the DAT0 will driven to LOW as BUSY status, and in sdhci specification, the transfer complete bit should be wait for BUSY status de-assert.
All response-with-busy commands don't contain data, the data judgement is no need.
