virtio-mem: keep retrying on offline_and_remove_memory() errors in Sub Block Mode (SBM)
In case offline_and_remove_memory() fails in SBM, we leave a completely
unplugged Linux memory block stick around until we try plugging memory
again. We won't try removing that memory block again.
offline_and_remove_memory() may, for example, fail if we're racing with
another alloc_contig_range() user, if allocating temporary memory fails,
or if some memory notifier rejected the offlining request.
Let's handle that case better, by simple retrying to offline and remove
such memory.
Tested using CONFIG_MEMORY_NOTIFIER_ERROR_INJECT.
