mm/sparse: remove WARN_ONs from (online|offline)_mem_sections()
We do not allow offlining of memory with memory holes, and always hotplug
memory without holes.
Consequently, we cannot end up onlining or offlining memory sections that
have holes (including invalid sections). That's also why these WARN_ONs
never fired.
Let's remove the WARN_ONs along with the TODO regarding double-checking.
