socketutils: do not request NDIAG_SHOW_MEMINFO

Browse Source 
This information is not used and it looks like it negatively affects
ability to find the socket under high load.

* socketutils.c (netlink_send_query) <req>: Remove NDIAG_SHOW_MEMINFO
flag from netlink_diag_req.ndiag_show field.
* tests/netlink_netlink_diag.c (send_query) <req>: Likewise.
