scsi: mptsas: Fixup device hotplug for VMWare ESXi
VMWare ESXi emulates an mptsas HBA, but exposes all drives as
direct-attached SAS drives. This it not how the driver originally
envisioned things; SAS drives were supposed to be connected via an
expander, and only SATA drives would be direct attached. As such, any
hotplug event for direct-attach SAS drives was silently ignored, and
the guest failed to detect new drives from within a VMWare ESXi
environment.
[Test]
The patch has been verified based on the Ubuntu kernel v4.4.0-97.120.
