Jakub Sitnicki 5d3919a953 selftests/bpf: Test freeing sockmap/sockhash with a socket in it ... Commit 7e81a35302 ("bpf: Sockmap, ensure sock lock held during tear down") introduced sleeping issues inside RCU critical sections and while holding a spinlock on sockmap/sockhash tear-down. There has to be at least one socket in the map for the problem to surface. This adds a test that triggers the warnings for broken locking rules. Not a fix per se, but rather tooling to verify the accompanying fixes. Run on a VM with 1 vCPU to reproduce the warnings.
