Subject: scsi: hisi_sas: Increase debugfs_dump_index after dump is completed

Git-commit: 9aec5ffa6e39926cff1a6b576c815a9cee90e259

Patch-mainline: v5.16-rc1

References: bsc#1198806

The hisi_hba debugfs_dump_index member should increased after a dump

insertion completed, and not before it has started, so fix the code to do

so.
