virtio-mem: convert most offline_and_remove_memory() errors to -EBUSY

Browse source

Just like we do with alloc_contig_range(), let's convert all unknown
errors to -EBUSY, but WARN so we can look into the issue. For example,
offline_pages() could fail with -EINTR, which would be unexpected in our
case.
