drbd: interval tree: make removing an "empty" interval a no-op
Trying to remove an "empty" (just initialized, or "cleared") interval
from the tree, this results in an endless loop.
As we typically protect the tree with a spinlock_irq,
the result is a hung system.
Be nice to error cleanup code paths, ignore removal of empty intervals.
