Sergey Vojtovich 54755c78cf BUG#11764339 - valgrind errors, random data when returning ...

ordered data from archive tables

Archive was using wrong memory address to check if field
is NULL (after filesort, when reading record again).

mysql-test/r/archive.result:
  A test case for BUG#11764339.
mysql-test/t/archive.test:
  A test case for BUG#11764339.
storage/archive/ha_archive.cc:
  Null bytes are restored to "record" buffer, which may
  or may not be equal to record buffer for field. Check
  null bits in "record" buffer, instead of Field::null_ptr.
