kmemleak: Do not warn if an unknown object is freed
vmap'ed memory blocks are not tracked by kmemleak (yet) but they may be released with vfree() which is tracked. The corresponding kmemleak warning is only enabled in debug mode. Future patch will add support for ioremap and vmap. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
