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.
