[PATCH net-next] net/socket.c: Remove an unused header file <linux/if_frad.h>

[Xie He]

This header file is not actually used in this file. Let's remove it.

Information about this header file:

This header file comes from the "Frame Relay" module at
  drivers/net/wan/dlci.c

The "Frame Relay" module is used by only one hardware driver, at:
  drivers/net/wan/sdla.c

Note that the "Frame Relay" module is different from and unrelated to the
"HDLC Frame Relay" module at:
  drivers/net/wan/hdlc_fr.c

I think maybe we can deprecate the "Frame Relay" module because we already
have the (newer) "HDLC Frame Relay" module.
