From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
This patch adds XDWRITEREAD_32 support to scsi_debug.c in
scsi_debug_queuecommand(). It follows the other READ_32 and WRITE_32
emulation for VARIABLE_LENGTH_CMD, and adds a simple goto back to existing
XDWRITEREAD_10 processing logic which already properly supports 64-bit LBA
and 32-bit transfer length in get_data_transfer_info()
