doc: fix sysfs ABI documentation
In 4.9 kernel, the sysfs files for Hyper-V VMBus changed name but
the documentation files were not updated. The current sysfs file
names are /sys/bus/vmbus/devices/<UUID>/...
See commit 9a56e5d6a0ba ("Drivers: hv: make VMBus bus ids persistent")
and commit f6b2db084b ("vmbus: make sysfs names consistent with PCI")
