[PATCH 3/3] scsi: Use try_rc16 and try_vpd_pages quirks on Hyper-V virtual disks

Microsoft Hyper-V virtual disks currently only claim SPC-2 compliance causing
feature tests not to be run (even though those features are correctly announced
elsewhere). Make Hyper-V virtual disks quirk past READ CAPACITY(16) and VPD
page guards so appropriate tests are performed.

This only impacts Hyper-V's VHD/VHDX virtual disks and not passthrough devices.
