    OpenBSD: Clean up use of LK_CANRECURSE in call to lockmgr()
    
    The LK_CANRECURSE and LK_RECURSEFAIL flags in the call to lockmgr()
    are mutually exclusive. Previous version of OpenBSD didn't really
    check well for this but more recent versions look for the conflict
    and take a kernel panic when they're both set.
    
    The OpenBSD kernel module currently just blindly sets the
    LK_CANRECURSE flag in its call to lockmgr(). This patch changes
    that behaviour so that it checks to make sure that the LK_RECURSEFAIL
    flags is not set before it actually applies the LK_CANRECURSE flag.
    That removes the kernel panics that have started to arise.
    
    This behaviour is more consistent with other OpenBSD code that makes
    use of the LK_CANRECURSE flag.
