ion: Limit max active to 1 for the buffer freeing workers

Browse Source 
* This is not something time critical. The load of the workqueues can
sometimes be very high, especially when unbound workqueues are restricted
to small cluster, bringing notable lags to userspace. Limit it with
max_active = 1 to reduce the instantaneous load.

* This fixes UI lags after running faceunlock on OOS.
