similar to: [PATCH v1] MAINTAINERS: Add myself as virtio-balloon co-maintainer

Changes to mm/balloon_compaction.c can easily break virtio, and virtio is the only user of that interface. Add a line to MAINTAINERS so whoever changes that file remembers to copy us.

This patch is a revert of 'commit bb01b64cfab7 ("mm/balloon_compaction.c: enqueue zero page to balloon device")' Ballooned pages will be marked as MADV_DONTNEED by the hypervisor and shouldn't be given to the host ksmd to scan. Therefore, it is not necessary to zero ballooned pages, which is very time consuming when the page amount is large. The ongoing fast balloon tests

I've been doing a lot of the development on vhost-scsi the last couple of years, so per Michael T's suggestion this adds me as co-maintainer.

Ballooned pages will be marked as MADV_DONTNEED by the hypervisor and shouldn't be given to the host ksmd to scan. Therefore, it is not necessary to zero ballooned pages, which is very time consuming when the page amount is large. The ongoing fast balloon tests show that the time to balloon 7G pages is increased from ~491ms to 2.8 seconds with __GFP_ZERO added. So, this patch removes the flag.
