NFSD: Annotate caller preconditions for the state-table walkers

Browse source

The state-table walkers now assert nfsd_mutex with
lockdep_assert_held() and document the nfsd_mutex / nn->nfsd_serv
precondition in a Context: kdoc section, so the next caller added to
this path cannot silently reintroduce the same use-after-free.
