MDEV-16940 Server crashes in unsafe_key_update upon attempt to update view
through 2nd execution of SP
This bug caused a server crash on the second call of any stored procedure
that contained an UPDATE statement over a multi-table view reporting an
error message at the prepare stage.
On the first call of the stored procedure after reporting an error at
the preparation stage of the UPDATE statement finished without calling
the function SELECT_LEX::save_prep_leaf_tables() for the SELECT used as
the definition of the view. This left the SELECT_LEX structure used by
the UPDATE statement in an inconsistent state for second call of the stored
procedure.
