Fix for BUG#32880 - Repairing Archive table fails with internal error 144

Browse source 
Any statement reading corrupt archive data file
(CHECK/REPAIR/SELECT/UPDATE/DELETE) may cause assertion
failure in debug builds. This assertion has been removed
and an error is returned instead.

Also fixed that CHECK/REPAIR returns vague error message
when it mets corruption in archive data file. This is
fixed by returning proper error code.

mysql-test/r/archive.result:
  A test case for BUG#32880
mysql-test/std_data/bug32880.ARN:
  corrupted archive table to test check and repair table operation
mysql-test/std_data/bug32880.ARZ:

mysql-test/std_data/bug32880.frm:
  corrupted archive table to test check and repair table operation
mysql-test/t/archive.test:
  A test case for BUG#32880
storage/archive/ha_archive.cc:
  Fixed unpack_row() to return the error instead of throwing assertion 
  and also fixed repair() to throw better error when repair table
  operation fails on corrupted archive table
