Modified Files:
	src/sys/kern: kern_lock.c
	src/sys/sys: lock.h

Log Message:
Nothing uses shared -> exclusive upgrades any more, so remove the code.
This is good since they are effectively the same as ...

	lockmgr(&lock, LK_RELEASE);
	lockmgr(&lock, LK_EXCLUSIVE);

.. and therefore don't behave as expected.
