MDEV-7620: Remove the data structures

Browse source 
The instrumentation that was added in
commit 90635c6fb5 (MDEV-7620)
was effectively reverted in MariaDB Server 10.2.2, in
commit 2e814d4702
(which stopped reporting the statistics) and
commit fec844aca8
(which stopped updating the statistics).

Let us remove the orphan data members to reduce the memory footprint.
