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.
