Kuniyuki Iwashima 68aeb21ef0 udp: Don't pass udptable to IPv4 socket lookup functions.
Since UDP and UDP-Lite had dedicated socket hash tables for
each, we have had to pass the pointer down to many socket
lookup functions.

UDP-Lite gone, and we do not need to do that.

Let's fetch net->ipv4.udp_table only where needed in IPv4
stack: __udp4_lib_lookup(), __udp4_lib_mcast_deliver(),
and udp_diag_dump().

Some functions are renamed as the wrapper functions are no
longer needed.

  __udp4_lib_err()     -> udp_err()
  __udp_diag_destroy() -> udp_diag_destroy()
  udp_dump_one()       -> udp_diag_dump_one()
  udp_dump()           -> udp_diag_dump()
