Subject: [PATCH] target: Make target_do_xcopy failures return
 INVALID_PARAMETER_LIST

This patch changes target_do_xcopy() to properly return
TCM_INVALID_PARAMETER_LIST instead of TCM_INVALID_CDB_FIELD
for failures related to the EXTENDED_COPY parameter list parsing.

Also, move struct xcopy_op allocation ahead of kmapping to
handle the special TCM_OUT_OF_RESOURCES case.
