Subject: [PATCH] kvm_host: Disable bluetooth kernel modules

Some IoT devices communicate through bluetooth so adapters are required
for host machines and passed through to virtual machines.

This patch prevents host to bluetooth kernel modules so adapters are not
in use and available for virtual machines.
