Ondrej Mosnacek 1aabe0f850 cipso: fix total option length computation
[ Upstream commit 9f36169912331fa035d7b73a91252d7c2512eb1a ]

As evident from the definition of ip_options_get(), the IP option
IPOPT_END is used to pad the IP option data array, not IPOPT_NOP. Yet
the loop that walks the IP options to determine the total IP options
length in cipso_v4_delopt() doesn't take IPOPT_END into account.

Fix it by recognizing the IPOPT_END value as the end of actual options.
