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.
