I forgot to add, there is also a small fix to the 
cipso_v4_sock_delattr() function so that it correctly removes the CIPSO 
option and either adjust the option padding correctly or removes the 
options struct entirely from the socket if it is no longer needed.

Thanks to Casey Schaufler for finding this bug.
