[PATCH 1/1] scsi: hisi_sas: Increase debugfs_dump_index after dump is completed

[Ike Panhc]

From: Luo Jiaxing <luojiaxing at huawei.com>

BugLink: https://launchpad.net/bugs/1982070

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.
