MDEV-20194 Warnings inconsistently issued upon CHECK on table from older versions

Browse Source 
The following condition has to added:
1) InnoDB fails to include the offset of the node pointer field
in non-leaf record for redundant row format.

2) If the Fixed length field does have only prefix length then
calculate the field maximum size as prefix length.

- Added the test case to test (2) and to check maximum number of
fields can exist in the index.
