Title: Validate Serial No Status

@nabinhait, @rmehta
Looking at #1564 made me look for a server side validation of serial no status change. I couldn't find it. Does this look okay? What about validation for Purchase Returned and Sales Returned?

Also, I can't think of how this will impact Serial No import.
