staging: rtl8192e: Fix compiler warning truncated writing of iwe.u.name

Browse source 
iwe.u.name and proto_name have both 16 bytes of space. But when writing
to iwe.u.name the first 10 bytes are used by the fixed string
"IEEE802.11". Evaluating the code shows that only the following strings
can occur in proto_name: "N-24G", "g", "b", "bg". Therefore it is
sufficient to shorten proto_name to 6 bytes.
