After removing capability check for fd migration the code that was left behind didn't make quite sense. The old exec migration would be used in case when pipe() failed. Remove the old code and make failure of pipe() a hard error. This additionally removes usage of virCgroupAllowDevicePath outside of qemu_cgroup.c.
