[PATCH 0/2] nfsd: proper fix for NULL deref in svc_pool_stats_start()

[NeilBrown <neilb@xxxxxxx>]

A recent patch attempted to fix a NULL pointer deref but introduced a
different NULL pointer deref and a possible unbalance unlock.

This series fixes the bug correctly and reverts the faulty fix.

(Sorry for not reviewing this patch earlier)
