wasm: correctly get the type of a local for free

When determining the type of a local (read: register), we would
previously subtract the stack locals also. However, this locals
are also within the same `locals` list, meaning the type of the
local we were retrieving was off by 2. This could create a validation
error when we re-use a local of a different type.
