nfsd: allow disabling NFSv2 at compile time
rpc.nfsd stopped supporting NFSv2 a year ago. Take the next logical step toward deprecating it and allow NFSv2 support to be compiled out. Add a new CONFIG_NFSD_V2 option that can be turned off and rework the CONFIG_NFSD_V?_ACL option dependencies. Add a description that discourages enabling it. Also, change the description of CONFIG_NFSD to state that the always-on version is now 3 instead of 2. Finally, add an #ifdef around "case 2:" in __write_versions. When NFSv2 is disabled at compile time, this should make the kernel ignore attempts to disable it at runtime, but still error out when trying to enable it.
