qemu_cgroup: Kill qemuSetupHostSCSIDeviceCgroup
qemu_cgroup: Kill qemuSetupHostSCSIDeviceCgroup

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