Subject: Revert "[SCSI] mpt3sas: Remove phys on topology change"

From: Sreekanth Reddy <[email protected]>

commit 2311ce4d9c91ed63a46e18f0378f3e406e7e888e upstream.

This reverts commit 963ba22b90a955363644cd397b20226928eab976
("mpt3sas: Remove phys on topology change")

Reverting the previous mpt3sas drives patch changes,
since we will observe below issue

Issue:
Drives connected Enclosure/Expander will unregister with
SCSI Transport Layer, if any one remove and add expander
cable with in DMD (Device Missing Delay) time period or
even any one power-off and power-on the Enclosure with in
the DMD period.
