scsi: qla2xxx: Fix qla24xx_process_bidir_cmd()

[ Upstream commit c29282c65d1cf54daeea63be46243d7f69d72f4d ]

Set the r??_data_len variables before using these instead of after.

This patch fixes the following Coverity complaint:

const: At condition req_data_len != rsp_data_len, the value of req_data_len
must be equal to 0.
const: At condition req_data_len != rsp_data_len, the value of rsp_data_len
must be equal to 0.
dead_error_condition: The condition req_data_len != rsp_data_len cannot be
true.
