Bluetooth: hci_sync: Only allow hci_cmd_sync_queue if running

Browse source

[ Upstream commit d883a4669a ]

This makes sure hci_cmd_sync_queue only queue new work if HCI_RUNNING
has been set otherwise there is a risk of commands being sent while
turning off.

Because hci_cmd_sync_queue can no longer queue work while HCI_RUNNING is
not set it cannot be used to power on adapters so instead
hci_cmd_sync_submit is introduced which bypass the HCI_RUNNING check, so
it behaves like the old implementation.
