storage/watchable_store: defer to Unlock s.mu

Browse Source 
New PR from https://github.com/coreos/etcd/pull/3575.
This add `defer` to `s.mu`. Current code does not `Unlock`
in the correct scope, I think.

(Sorry, I accidentally deleted my fork so the changes
might not sound continuous from my previous pull requests.)
