This series intends to fix the race between the MHI stack and the MHI client
drivers due to the MHI 'auto_queue' feature. As it turns out often, the best
way to fix an issue in a feature is to drop the feature itself and this series
does exactly that.

There is no real benefit in having the 'auto_queue' feature in the MHI stack,
other than saving a few lines of code in the client drivers. Since the QRTR is
the only client driver which makes use of this feature, this series reworks the
QRTR driver to manage the buffer on its own.
