Bluetooth: hci_sync: Add a new quirk to skip HCI_FLT_CLEAR_ALL
Some controllers have problems with being sent a command to clear
all filtering. While the HCI code does not unconditionally
send a clear-all anymore at BR/EDR setup (after the state machine
refactor), there might be more ways of hitting these codepaths
in the future as the kernel develops.
