Subject: lib/interval_tree: fix allocation warning messages

WARN_ON_ONCE() takes a condition, not a message.  The string literals are
always true, so the warnings still trigger but the messages are never
printed.

Use WARN_ONCE(1, ...) instead to print the messages and keep the once-only
behavior.

Found with a Coccinelle script.  Clang's -Wstring-conversion also flags
such calls but is not enabled in kernel builds.
