Vlad Yasevich 5f19d1219a SCTP: Free the per-net sysctl table on net exit. v2 ...

Per-net sysctl table needs to be explicitly freed at
net exit.  Otherwise we see the following with kmemleak:

unreferenced object 0xffff880402d08000 (size 2048):
  comm "chrome_sandbox", pid 18437, jiffies 4310887172 (age 9097.630s)
  hex dump (first 32 bytes):

I fixed the spelling of sysctl_header so the code actually
compiles. -- EWB.
