Subject: Bluetooth: btusb: Detect if an ACL packet is in fact an ISO packet
Patch-mainline: v6.0-rc1
Git-commit: 14202eff214e1e941fefa0366d4c3bc4b1a0d500
References: jsc#PED-1407

Fix up the packet type if ISO packets are sent over the bulk endpoint.

Note: This is a stopgap since the Bluetooth specification currently
doesn't define any endpoint to transport ISO packets.
