Bluetooth: btusb: Remove detection of ISO packets over bulk

[ Upstream commit efe375b716c1c1c9b52a816f5b933a95421020a2 ]

This removes the code introduced by
14202eff214e1e941fefa0366d4c3bc4b1a0d500 as hci_recv_frame is now able
to detect ACL packets that are in fact ISO packets.

Fixes: 14202eff214e ("Bluetooth: btusb: Detect if an ACL packet is in fact an ISO packet")
