In PC-BSD 9.1, VIMAGE is enabled in the kernel config.
For laptops with Bluetooth capability, such as the HP Elitebook 8460p,
the kernel will panic upon bootup, because curthread->td_vnet
is not initialized.
Properly initialize curthread->td_vnet when initializing the Bluetooth stack.
This allows laptops such as the HP Elitebook 8460p laptop
to properly boot with VIMAGE kernels.
