We now 'select SOCK_CGROUP_DATA' but Kconfig complains that this is
not right when CONFIG_NET is disabled and there is no socket interface:
warning: (CGROUP_BPF) selects SOCK_CGROUP_DATA which has unmet direct
dependencies (NET)
I don't know what the correct solution for this is, but simply removing
the dependency on NET from SOCK_CGROUP_DATA by moving it out of the
'if NET' section avoids the warning and does not produce other build
errors.

There was an earlier patch by Augusto Mecking Caringi, which added
a dependency, see https://lkml.org/lkml/2017/1/2/296.
I could not figure out whether CGROUP_BPF is meaningful without
CONFIG_NET, my version of the patch assumes that it is.
Applying either my version Augusto's to v4.10-rc will kill the
warning.
