Fix for bug #23412: delete rows with null date field

- test case
sql/sql_delete.cc:
Fix for bug #23412: delete rows with null date field
- during SELECT queries processing we convert 'date[time]_field is null'
conditions into 'date[time]_field = 0000-00-00[ 00:00:00]' for not null
DATE and DATETIME fields. To be consistent, we have to do the same for DELETE
queries. So we should call remove_eq_conds() in the mysql_delete() as well.
Also it may simplify and speed up DELETE queries execution.
