[net-2.6 PATCH 1/6] net: initialize rmem_alloc and omem_alloc to 0 in netlink socket

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: John Fastabend <john.r.fastabend@intel.com>

The rmem_alloc and omem_alloc socket fields are not
initialized.  This sets each variable to zero when a socket
is created.  Note the sk_wmem_alloc is already initialized
in sock_init_data.
