ip: limit use of gso_size to udp
The ipcm(6)_cookie field gso_size is set only in the udp path. The ip
layer copies this to cork only if sk_type is SOCK_DGRAM. This check
proved too permissive. Ping and l2tp sockets have the same type.
Limit to sockets of type SOCK_DGRAM and protocol IPPROTO_UDP to
exclude ping sockets.
v1 -> v2
- remove irrelevant whitespace changes
