scsi: storvsc: Remove support for Hyper-V 2008 and 2008R2/Win7

Browse source

The storvsc driver has special case code for running on the first released
versions of Hyper-V: 2008 and 2008 R2/Windows 7.  These versions are now
out of support (except for extended security updates) and lack support
for performance features like multiple VMbus channels that are needed for
effective production usage of Linux guests.

The negotiation of the VMbus protocol versions required by these old
Hyper-V versions has been removed from the VMbus driver.  So now remove
the handling of these VMbus protocol versions from the storvsc driver.
