BACKPORT [UPSTREAM] net: add real socket cookies
Cherry-pick from upstream commit 33cf7c90fe2f97afb1cadaa0cfb782cb9d1b9ee2.
Introduce a unique per netspace identifier for each socket and it is
required by xt_qtaguid module to identify the socket without holding the
socket reference count. The change is modified to the minimal impact so
that it doesn't change other socket networking behavior.
