Bluetooth: Perform HCI update for power on synchronously
The request to update HCI during power on is always coming either from hdev->req_workqueue or through an ioctl, so it's safe to use hci_req_sync for it. This way we also eliminate potential races with incoming mgmt commands or other actions while powering on. Part of this refactoring is the splitting of mgmt_powered() into mgmt_power_on() and __mgmt_power_off() functions. The main reason is the different requirements as far as hdev locking is concerned, as highlighted with the __ prefix of the power off API. Since the power on in the case of clearing the AUTO_OFF flag cannot be done synchronously in the set_powered mgmt handler, the hci_power_on work callback is extended to cover this (which also simplifies the set_powered helper a lot).
