Testing on a second host showed the internal/external split cannot be inferred: iz-pve1's MD1200 sits behind its own HBA while iz-pve0's internal drives sit behind a SAS expander, so the previous "pci-*-scsi-*" glob matched every drive on one host and none on the other. DISK_EXCLUDE_PATTERN now names the shelf's HBA per host. Also fixes parse_disk_limit, which used awk's for-in over split fields and so returned 0 or 70 from "0/70" depending on iteration order.
