crypto: qat - change value of default idle filter 

[ Upstream commit 0f942bdfe9 ]

The power management configuration of 4xxx devices is too aggressive
and in some conditions the device might be prematurely put to a low
power state.
Increase the idle filter value to prevent that.
In future, this will be set by firmware.

Fixes: e5745f3411 ("crypto: qat - enable power management for QAT GEN4")
