Log Message:
Prepare to stop using isr->sav

isr is a shared resource and using isr->sav as a temporal storage
for each packet processing is racy. And also having a reference from
isr to sav makes the lifetime of sav non-deterministic; such a reference
is removed when a packet is processed and isr->sav is overwritten by
new one. Let's have a sav locally for each packet processing instead of
using shared isr->sav.

However this change doesn't stop using isr->sav yet because there are
some users of isr->sav. isr->sav will be removed after the users find
a way to not use isr->sav.
