selftests: net: add a test for closing a netlink socket ith dump in progress
Close a socket with dump in progress. We need a dump which generates
enough info not to fit into a single skb. Policy dump fits the bill.
Use the trick discovered by syzbot for keeping a ref on the socket
longer than just close, with mqueue.
TAP version 13
1..3
# Starting 3 tests from 1 test cases.

# RUN global.close_with_ref ...
# OK global.close_with_ref
ok 3 global.close_with_ref
# PASSED: 3 / 3 tests passed.
# Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0
Note that this test is not expected to fail but rather crash
the kernel if we get the cleanup wrong.
