Fix a problem introduced when MFCing the rw_try_wlock() operation from
HEAD:
__rw_wunlock() relies on the cookie state to not be cleanly 'tid' when
some conditions needing of special care happens, and lock recursion is
among those.  Dirty the cookie by adding the RW_LOCK_RECURSE flag in the
case of a successfull try lock operation.

This is not a problem on -CURRENT and STABLE_8 where the unlocking
algorithm works differently.
