[PATCH 11/15] tty: serial: qcom-geni-serial: stop operations in progress at shutdown

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

We don't stop transmissions in progress at shutdown. This is fine with
FIFO SE mode but with DMA it causes trouble so fix it now.
