Bluetooth: hci_ldisc: Fix null pointer derefence in case of early data
commit 84cb3df02aea4b00405521e67c4c67c2d525c364 upstream.
HCI_UART_PROTO_SET flag is set before hci_uart_set_proto call. If we
receive data from tty layer during this procedure, proto pointer may
not be assigned yet, leading to null pointer dereference in rx method
hci_uart_tty_receive.
This patch fixes this issue by introducing HCI_UART_PROTO_READY flag in
order to avoid any proto operation before proto opening and assignment.
