sctp: fix incorrect overflow check on autoclose
Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for
limiting the autoclose value. If userspace passes in -1 on 32-bit
platform, the overflow check didn't work and autoclose would be set
to 0xffffffff.
This patch defines a max_autoclose (in seconds) for limiting the value
and exposes it through sysctl, with the following intentions.
1) Avoid overflowing autoclose * HZ.
2) Keep the default autoclose bound consistent across 32- and 64-bit
platforms (INT_MAX / HZ in this patch).
3) Keep the autoclose value consistent between setsockopt() and
getsockopt() calls.
