[jit] Minor: avoid recalculating some keys for map accesses in pickler. (#33060) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/33060 Noticed this when tracking down a partially-related SIGSEGV. If inserting a non-present key into a memoized map, don't re-calculate it twice (probably safer that way anyway). ghstack-source-id: 97904485 Test Plan: buck test mode/dev-nosan caffe2/test/...
