Bug 15207: Avoid warnings when adding constraint course_reserves_ibfk_2

Bug 14205 added a new foreign key on the course_reserve table.
As this dbrev has been backported to the stable version (3.20.x), the
next dbrev should take care of this existing constraint to avoid
warnings.

Test plan:
1/ replace the modified dbrev with 3.21.00.XXX to make sure it will be
executed
2/ Make sure you have the KEY and the FK on the course_reserves table:
sql> alter table course_reserves add CONSTRAINT `course_reserves_ibfk_2`
FOREIGN KEY (`ci_id`) REFERENCES `course_items` (`ci_id`) ON DELETE
CASCADE ON UPDATE CASCADE;
sql> alter table course_reserves ADD KEY `course_reserves_ibfk_2` (`ci_id`);

3/ SHOW CREATE TABLE course_reserves
should show that the table is not in sync with the kohastructure.sql file
4/ Execute the dbrev
5/ SHOW CREATE TABLE course_reserves
should show that the table is in sync with the kohastructure.sql file

Repeat 4 and 5, confirm you don't get any error.
