Do not destroy the strpool if NULL
It is possible that a debug info contains no string (and so strpool
is never allocated).
A protection to avoid accessing strpool was already necessary
in ML_(canonicaliseTables) :
So, if a similar debug info is released, we need the same protection
to avoid accessing a NULL strpool.
Detect by Julian on arm64, but not (at least easily) reproduced on amd64.
