From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
My security fix for the security.capability remap has a silly early
segfault in a simple case where there is an xattrmapping but it doesn't
remap the securty.capability.
Fixes: e586edcb41054 ("virtiofs: drop remapped security.capability xattr as
needed")
Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
