tcmu: Skip Data-Out blocks before gathering Data-In buffer for BIDI case

For the bidirectional case, the Data-Out buffer blocks will always at
the head of the tcmu_cmd's bitmap, and before gathering the Data-In
buffer, first of all it should skip the Data-Out ones, or the device
supporting BIDI commands won't work.

		data_length/data_head/data_tail")
