target: Add missing XCOPY I/O operation sense_buffer

This patch adds the missing xcopy_pt_cmd->sense_buffer[] required for
correctly handling CHECK_CONDITION exceptions within the locally
generated XCOPY I/O path.

Also update target_xcopy_read_source() + target_xcopy_setup_pt_cmd()
to pass this buffer into transport_init_se_cmd() to correctly setup
se_cmd->sense_buffer.
