APPLIED: [PATCH 0/1][FGHI][linux] scsi: storvsc: Parameterize number hardware queues

[Tim Gardner]

Applied to [FGHI][linux], [FGHI][linux-azure]. Thanks.

I applied this patch on the linux-azure branches in order to get it in 
the 2021-05-31 SRU cycle. The master-next branch updates are fine for 
the next SRU cycle.
