qemu_cgroup: Kill qemuSetupHostSCSIVHostDeviceCgroup

Browse Source 
There's no need for this function. Currently it is passed as a
callback to virSCSIVHostDeviceFileIterate(). However, SCSI host
devices have just one file path. Therefore we can mimic approach
used in qemuDomainGetHostdevPath() to get path and call
virCgroupAllowDevicePath() directly.
