mm: remove unused variable in memory hotplug

When I removed the per-zone bitlock hashed waitqueues in commit
9dcb8b685fc3 ("mm: remove per-zone hashtable of bitlock waitqueues"), I
removed all the magic hotplug memory initialization of said waitqueues
too.

But when I actually _tested_ the resulting build, I stupidly assumed
that "allmodconfig" would enable memory hotplug.  And it doesn't,
because it enables KASAN instead, which then disables hotplug memory
support.

As a result, my build test of the per-zone waitqueues was totally
broken, and I didn't notice that the compiler warns about the now unused
iterator variable 'i'.

I guess I should be happy that that seems to be the worst breakage from
my clearly horribly failed test coverage.
