ipa: raspberrypi: Fix bug in IPA frame drop logic

Browse Source 
Fix a bug in the IPA frame dropping (for rate control) logic, where the
metadata for the current context was copied from itself (i.e. a no-op), instead
of being copied from the previous context.

This bug does not occur in normal conditions, only when running with a low
exposure time and unconstrained framerate, which happens in a particular
picamera2 test.
