[PATCH 02/14] nfsd: Add missing gen_confirm in nfsd4_setclientid()

[Kinglong Mee <kinglongmee@gmail.com>]

Commit 294ac32e99 "nfsd: protect clid and verifier generation with client_lock"
have moved gen_confirm() to gen_clid().

After it, setclientid will return a bad reply with all zero confirms
after copy_clid().
