[PATCH] storvsc: Avoid excessive host scan on controller change

[Martin K. Petersen]

Long,

> When there are multiple disks attached to the same SCSI controller,
> the host may send several VSTOR_OPERATION_REMOVE_DEVICE or
> VSTOR_OPERATION_ENUMERATE_BUS messages in a row, to indicate there is
> a change on the SCSI controller. In response, storvsc rescans the SCSI
> host.

Applied to 4.15/scsi-queue with some fuzz. Please verify, thanks!
