Shawn.Shao 57054fe516 Add exception protection processing for vd in axi_chan_handle_err function 
Since there is no protection for vd, a kernel panic will be
triggered here in exceptional cases.

You can refer to the processing of axi_chan_block_xfer_complete function

The triggered kernel panic is as follows:
