 Description   

Patch http://review.whamcloud.com/15162 for LU-6602 introduced a new out_update operation OUT_NOOP, but did not add an entry to the out_update_ops table which now results in out_handler_find haning a potential buffer overflow.
Worse yet, once somebody adds another entry there, it'll likely cause a crash too.

This is not critical, but frequently enough to be a concern.

Can you please have a look?

Thanks.
