[VAR] Fix poplocalvar on abnormal exit from function
The new localvar code broke the abnormal exit from functions and built-ins by not restoring the original localvar state. This patch fixes this by storing the previous localvar state so that we always unwind correctly in case of an abnormal exit. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
