Bluetooth: hci_usb: Read the whole USB EPOUT buffer at once

btusb_bulk_out() reads the EPOUT buffer in multiple of 4 bytes because
of Quark's USB FIFO size limitation. But this has later been taken care
internally in the DW driver making it redundant in hci_usb.

Remove Quark specific handling and read the whole EPOUT buffer at once.
