Bluetooth: btnxpuart: Fix driver sending truncated data
This fixes the apparent controller hang issue seen during stress test
where the host sends a truncated payload, followed by HCI commands. The
controller treats these HCI commands as a part of previously truncated
payload, leading to command timeouts.
Adding a serdev_device_wait_until_sent() call after
serdev_device_write_buf() fixed the issue.
