Fix incomplete RMSNorm patch

[Tcc0403]

Summary

Fix #383, #390.
RMSNorm wasn't fully patched to already-instantiated modules, missing in_place attribute when patching.

Testing Done

Added an extra_expr test after patching an instantiated model

Thanks! This should fix #383 and #390. Will make a patch release after this
