Lorenzo Colitti 2f68f939e1 net: diag: Add the ability to destroy a socket.
This patch adds a SOCK_DESTROY operation, a destroy function
pointer to sock_diag_handler, and a diag_destroy function
pointer.  It does not include any implementation code.

[Backport of net-next 64be0aed59ad519d6f2160868734f7e278290ac1]
