Code refactorization:

Moved the code for ep 0 in ath10k_htc_rx_completion_handler
to ath10k_htc_control_rx_complete.

This eases the implementation of SDIO/mbox significantly since
the ep_rx_complete cb is invoked directly from the SDIO/mbox
hif layer.

Since the ath10k_htc_control_rx_complete already is present
(only containing a warning message) there is no reason for not
using it (instead of having a special case for ep 0 in
ath10k_htc_rx_completion_handler).

This should be squashed with Patch 3 since it's inseparable part of
the same refactorization.

Hmm, I don't really see why this is an inseparable part of the previous
patch.

As far as I see this patch has nothing to do with patch 3, or am I
missing anything?

Are you really sure they should be squashed?

Hmm.. on second thought this should be fine as it is.
