[patch] recv.2, cmsg.3: Fix type of cmsg_len member of cmsghdr structure

["Nikola Forró" <nforro-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

The type shown for cmsg_len member of cmsghdr structure is socklen_t,
but the actual type used by glibc and the kernel is size_t.

The information was obtained from glibc source code:
http://bit.ly/21m1RMp
