scripts/gdb: rename pool_index to pool_index_plus_1

Browse Source 
We encounter the following issue after commit a6c1d9cb9a ("stackdepot:
rename pool_index to pool_index_plus_1").

(gdb) lx-dump-page-owner --pfn 262144
...
Python Exception <class 'gdb.error'>: There is no member named pool_index.
Error occurred in Python: There is no member named pool_index.

We rename pool_index to pool_index_plus_1 to fix this issue.
