KVM: SEV: Fix page dirtying in sev_gmem_post_populate()
set_page_dirty() requires that the caller holds some kind of lock to
ensure that the page's mapping does not concurrently go away.
That is not the case for a random page we got from get_user_pages_fast(),
so use set_page_dirty_lock().
Fixes: 97cd21d57e9b ("KVM: SEV: Mark source page dirty when writing back CPUID data on failure")
