dax: Make sure the unlocking entry isn't locked
I wrote the semantics in the commit message, but didn't document it in the source code. Use a BUG_ON instead (if any code does do this, it's really buggy; we can't recover and it's worth taking the machine down). Signed-off-by: Matthew Wilcox <willy@infradead.org>
