Subject: [PATCH v2 2/3] scripts/gdb/stackdepot: Rename pool_index to pools_num

After stackdepot evicting support patchset[1], we rename
pool_index to pools_num.

To avoid from the below issue, we rename consistently in
gdb scripts.

Python Exception <class 'gdb.error'>: No symbol "pool_index" in current
context.
Error occurred in Python: No symbol "pool_index" in current context.
