[PATCH char-misc-next 4/4] mei: me: reduce active polling timeout to 20 ms

[Alexander Usyskin]

Improve performance of polling by reducing active timeout.
20 ms active timeout helps increase channel throughtput
and significately reduces data transfer times.

Our tests have prooved that timeout decrease does no ill effects
for core CPU utilization.
