i2c: Factor our send() and recv() common logic
Most of the control flow logic between send and recv (error checking
etc) is the same. Factor this out into a common send_recv() API.
This is then usable by clients, where the control logic for send
and receive differs only by a boolean. E.g.
if (send)
i2c_send(...):
else
i2c_recv(...);
becomes:
i2c_send_recv(... , send);
