Removed implicit divisions in the residual echo detector

Removed implicit divisions in the residual echo detector

This CL changes the updating of a loop index from using the modulus
operator to using a conditional, avoiding the divisions done in the 
modulus operator which had a measurable impact on mpbile
platforms.

Additionally, there is a similar removal of another modulus operator, but the impact of that should be negligible.

ivoc@: Could you PTAL  on this CL. It aims at reducing the APM complexity on
mobile platforms.

[ivoc, 2017-05-16 13:28:24]

LGTM.
