manta: libcamera2: fix copy-and-paste regression

In "manta: libcamera2: if captured shot drained, record current shot data"
m_reprocessingFrameCnt was taken from previous fragment and not replaced
in the new context with shot_ext->shot.ctl.request.frameCount. This resulted
in CTS:android.hardware.cts.CameraTest@testJpegExif failures.
