Add a check in witness to allow taking a lock recursively

When using a recursive lock, witness trigger an errors if the lock is taken
twice although it is an expected case.

This was observed when using a rm_lock created with the RM_RECURSE flag.
So I add a check in witness to check is the class of the lock have the
LC_RECURSABLE flag set before triggering the error.

Note that this is a quick fix which could probably be enhanced.
