Bluetooth: hci_qca: Fix crash with non-serdev devices
qca_set_baudrate() calls serdev_device_wait_until_sent() assuming that the HCI is always associated with a serdev device. This isn't true for ROME controllers instantiated through ldisc, where the call causes a crash due to a NULL pointer dereferentiation. Only call the function when we have a serdev device. The timeout for ROME devices at the end of qca_set_baudrate() is long enough to be reasonably sure that the command was sent.
