Improve third-party copy error reporting.

For EXTENDED COPY:
 - improve parameters checking to report some errors before copy start;
 - forward sense data from copy target as descriptor in case of error;
 - report which CSCD reported error in sense key specific information.
For WRITE USING TOKEN:
 - pass through real sense data from copy target instead of reporting
our copy error, since for initiator its a "simple" write, not a copy.
