[Bluetooth] Remove USB zero packet option

This patch removes the USB zero packet option from the HCI USB
Bluetooth driver, because it is useless. It also corrects the
config name of the SCO audio support.

This option enables the SCO support in the HCI USB driver. You need this
to transmit voice data with your Bluetooth USB device.

This option is provided only as a work around for buggy Bluetooth USB
devices. Do _not_ enable it unless you know for sure that your device
requires zero packets.
