Fix electron beam crash
Under certain circumstances the ICS SurfaceFlinger attempts to disable
the hwc module by calling prepare with the list set to NULL. This code
path is specifically used by the Electron Beam screen off animation.
Since blit_reset() is just checking for a geometry change, this patch
handles the list pointer null case.
Reproducible with:
service call SurfaceFlinger 8 i32 1
(Thanks Jon & Michael!)
