Change FBC idle mode back to default 

Use the "immediate idle" mode for FBC.  Rather than waiting for the current
compression pass to finish before signalling to the CPU that it's idle, this
mode should stop any current compression pass and tell the CPU that the GPU is
idle right away.

Seems to fix #13326.
