[PATCH bpf v4 0/2] bpf, sockmap: fix potential memory leak

While investigating a memleak in sockmap I found these two issues. Patch
1 found doing code review, I wasn't able to get KASAN to trigger a
memleak here, but should be necessary. Patch 2 fixes proc stats so when
we use sockstats for debugging we get correct values.

The fix for observered memleak will come after these, but requires some
more discussion and potentially patch revert so I'll try to get the set
here going now.

v4: fix both users of sk_psock_skb_ingress_enqueue and then fix the
    inuse idx by moving init hook later after tcp/udp init calls.
v3: move kfree into same function as kalloc
