[ Upstream commit 8cb38a602478e9f806571f6920b0a3298aabf042 ]
The patch(180d8cd942ce) replaces all uses of struct sock fields' memory_pressure, memory_allocated, sockets_allocated, and sysctl_mem to accessor macros. But the sockets_allocated field of sctp sock is not replaced at all. Then replace it now for unifying the code.
Fixes: 180d8cd942ce ("foundations of per-cgroup memory pressure controlling.")
