====================
sctp: Some sockopt optlen fixes

Hangbin Liu reported that some SCTP sockopt are allowing the user to get
the kernel to allocate really large buffers by not having a ceiling on
optlen.

This patchset address this issue (in patch 2), replace an GFP_ATOMIC
that isn't needed and avoid calculating the option size multiple times
in some setsockopt.
