SVN rev 192683 on 2009-05-24 12:33:16Z by kib
In lf_advlockasync(), recheck for doomed vnode after the state->ls_lock
is acquired. In the lf_purgelocks(), assert that vnode is doomed and set
*statep to NULL before clearing ls_pending list. Otherwise, we allow for
the thread executing lf_advlockasync() to put new pending entry after
state->ls_lock is dropped in lf_purgelocks().
