If no suitable FVB protocol implementation is found to apply the capsule
update, and the last one we disregarded was ruled out because it has the
read-only attribute, we will exit the function returning EFI_SUCCESS
without assigning a value to *OutFvb, resulting in a crash when it
subsequently gets dereferenced. So set the correct value for Status for
that case.
