[ Upstream commit 96dddb7b9406259baace9a1831e8da155311be6f ]
When checking MTE tags, we print some diagnostic messages when the tests fail. Some variables uses there are "longs", however we only use "%x" for the format specifier.
Update the format specifiers to "%lx", to match the variable types they are supposed to print.
