Increase-debugfs_dump_index-after-dump 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4NDP8


CVE: NA

-------------------

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.
