mm: use 'const char *' insted of 'char *' for reason in dump_page()
I tried to use 'dump_page(page, __func__)' for debugging, but it triggers
warning:
warning: passing argument 2 of `dump_page' discards `const' qualifier from pointer target type [enabled by default]
Let's convert 'reason' to 'const char *' in dump_page() and friends: we
shouldn't modify it anyway.
