Subject: sctp: Replace use of sockets_allocated with specified macro.
From: Tonghao Zhang <xiangxia.m.yue@xxxxxxxxx>
[ 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.")
