Al reported that he had seen some LTP fcntl11 and fcntl21 test
failures since the merge window had opened.
In the case where we're splitting a lock in two, the current code
the new "left" lock in the incorrect spot. It's inserted just
before "right" when it should instead be inserted just before the
new lock.
When we add a new lock, set "fl" to that value so that we can
add "left" before it.
