sqlcache: also ignore integrity error

integrity error can happens when multiple client tries to warm similar cache.
Given we leave multiple hole in the cache that can be warmed by anyone, this is
harder to avoid that we would like. We simply catch the error in this case.
Someone will warm the missing entry later.
