gnss: serial: fix synchronous write timeout commit 56a6c7268312cba9436b84cac01b3e502c5c511d upstream. Passing a timeout of zero to the synchronous serdev_device_write() helper does currently not imply to wait forever (unlike passing zero to serdev_device_wait_until_sent()). Instead, if there's insufficient room in the write buffer, we'd end up with an incomplete write.
