FOLLOW-UP FIX FOR BUG#27141613
PROBLEM
Issue found during ntest run is a regression of Bug #27141613. The
issue is basically when index is being freed due to an error during its
creation,when the index isn't added to dictionary cache its field
columns are not set, the derefrencing of null col pointer during the
clean of index from the virtual column's leads to a crash.
NOTE: Also test i_innodb.virtual_debug was failing on 32k page size and
above for the newly added scenario. Fixed that.
FIX
Added a check that if only the index is cached , the virtual index
freeing from the virtual cols index list is performed.
