Bluetooth: hci_serdev: clear HCI_UART_PROTO_READY to avoid closing proto races
Clearing HCI_UART_PROTO_READY will avoid usage of proto function pointers before running the proto close function pointer. There is chance of kernel crash, due to usage of non proto close function pointers after proto close.
