net: ipa: kill replenish_saved
The replenish_saved field keeps track of the number of times a new buffer is added to the backlog when replenishing is disabled. We don't really use it though, so there's no need for us to track it separately. Whether replenishing is enabled or not, we can simply increment the backlog. Get rid of replenish_saved, and initialize and increment the backlog where it would have otherwise been used. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.
