commit 94e6e889a786dd16542fc8f2a45405fa13e3bbb5 upstream.
If an inactive rsb is not hashed anymore and this could occur because we releases and acquired locks we need to signal the followed code that the lookup failed. Since the lookup was successful, but it isn't part of the rsb hash anymore we need to signal it by setting error to -EBADR as dlm_search_rsb_tree() does it.
