tcmu: Skip Data-Out blocks before gathering Data-In buffer for BIDI case
commit a5d68ba85801a78c892a0eb8efb711e293ed314b upstream.
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.
Fixed: 26418649eead ("target/user: Introduce data_bitmap, replace
data_length/data_head/data_tail")
