ipv4: Simplify iph->daddr overwrite in ip_options_rcv_srr().

Browse Source 
We already copy the 4-byte nexthop from the options block into
local variable "nexthop" for the route lookup.

Re-use that variable instead of memcpy()'ing again when assigning
to iph->daddr after the route lookup succeeds.
