[PATCH] knfsd: SUNRPC: Provide room in svc_rqst for larger addresses

Browse Source 
Expand the rq_addr field to allow it to contain larger addresses.

Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then
everywhere the 'sockaddr_in' was referenced, we use instead an accessor
function (svc_addr_in) which safely casts the _storage to _in.
