When dlm_release_lockspace(ls, 1) is invoked on a busy system immediately after the last dlm_unlock() AST has finished it can occur that lkb_idr_is_local() is invoked for the unlocked LKB since removal from ls_lkbidr only occurs after the AST has returned. If that happens dlm_release_lockspace(ls, 1) will return -EBUSY instead of releasing the lockspace. Fix this race condition by changing lkb_idr_is_local() such that it only returns true for LKB's that have not yet been unlocked.
