Aleksey Midenkov dd9773b723 MDEV-22413 Server hangs upon UPDATE on a view reading from versioned partitioned table

UPDATE gets access to history records because versioning conditions
are not set for VIEW. This leads to endless loop of inserting history
records when clustered index is rebuilt and ha_rnd_next() returns
newly inserted history record.

Return back original behavior of failing on write-locked table in
historical query.

35b679b9 assumed that SELECT_LEX::lock_type influences anything, but
actually at this point table is already locked. Original bug report
was tempesta-tech/mariadb#102
