inlink->format is supposed to be set to a valid format controlled by query_formats().

This reverts commit 04f00022, which made it impossible to enable VSX with

Inconsistencies between the dimensions/pixel format of avctx and the
frame can confuse API users.
For example this can crash the demuxing_decoding example.

Back up the previous values and restore them, when decoding the next
frame. This is necessary, because these can be different between the
returned frame and the last decoded frame.
