Documentation: hyperv: Update information on guest CPU offlining

Browse Source 
In Hyper-V Overview documentation, remove the out-of-date reference
to explicitly reassigning VMBus channel interrupts before taking a
guest CPU offline. Instead, reference the VMBus documentation, which
is already up-to-date on this topic.

only the CPUs actually present in the VM, so Linux does not report
any hot-add CPUs.
A Linux guest CPU may be taken offline using the normal Linux
mechanisms, provided no VMBus channel interrupts are assigned to
the CPU. See the section on VMBus Interrupts for more details
on how VMBus channel interrupts can be re-assigned to permit
taking a CPU offline.
A Linux guest CPU may be taken offline, and subsequently brought
back online, using the normal Linux mechanisms. See the "VMBus
Interrupts" section of Documentation/virt/hyperv/vmbus.rst
documentation for how VMBus channel interrupts are automatically
re-assigned if necessary when taking a CPU offline.
