There is no need to copy the whole memslot data after releasing
slots_arch_lock for a moment to install temporary memslots copy in
kvm_set_memslot() since this lock only protects the arch field of each
memslot.
Just resync this particular field after reacquiring slots_arch_lock.
Note, this also eliminates the need to manually clear the INVALID flag
when restoring memslots; the "setting" of the INVALID flag was an
unwanted side effect of copying the entire memslots.

[sean: tweak shortlog, note INVALID flag in changelog, revert comment]
This updated patch also open-codes kvm_copy_memslots(), which my
previous version didn't.
I think it's worth mentioning this in the change log, too.
Thanks,
Maciej
