[PATCH v2] storvsc: Set up correct queue depth values for IDE devices

From: Long Li Unlike SCSI and FC, we don't use multiple channels for IDE. Also fix the calculation for sub-channels. Change log: v2: Addressed comment on incorrect number of sub-channels. (Michael Kelley ) Signed-off-by: Long Li
