s390/topology: Use zero-based numbering for containing entities (2026-05-20 09:39:24 +0200)

----------------------------------------------------------------
s390 fixes for 7.1-rc5

- Fix PAI NNPA mismatch between counting and recording, where
sampling reports twice the value

- Fix loss of PAI counter increments during recording on systems
with many CPUs under heavy load, while counting is not affected

- On some supported machines, CHSC cannot access memory outside
the DMA zone, causing CHSC command failures. Restore GFP_DMA
flag when allocating memory for CHSC control blocks

- Align the numbering scheme for higher-level topology structures
like socket, book, drawer with other hardware identifiers e.g.
in sysfs, procfs and tools like lscpu
