deinterlace: fix infinite loop on EOS with non-default methods or fields

Browse source 
Fixes problem of infinite loop in gst_deinterlace_reset_history.
Last field in the history was never deinterlaced because idx becomes negative.

Happens e.g. with method=scalerbob fields=bottom or
method=greedyl fields=top
