39f0182303 hyperv/storvsc: The max channel in PDU actually means the max sub-chans. 
Use proper name for local variables. PDU fields' name was not changed yet.
While I'm here, make # of usable channels tunable. This eases further
testing.

692cb24f10 hyperv/storvsc: Fix the SCSI disk attachment issue. 
On pre-WS2016 Hyper-V, if the only LUNs > 7 are used, then all disks
fails to attach.  Mainly because those versions of Hyper-V do not set
SRB_STATUS properly and deliver junky INQUERY responses.
