kmssink: Fix fallback path for driver not able to scale scenario

Browse source 
When driver return error on update plane request, kmssink
disables the scaling and retries plane update.
While doing so kmssink was matching the source rectangle dimensions
to the target rectangle dimensions which were calculated
as per scaling but this is incorrect, instead what we want here is
that target rectangle dimensions should match the source rectangle
dimensions as scaling is disabled now and so we match result
rectangle dimensions with source rectangle dimensions.

While at it, also match the result rectangle coordinates for
horizontal and vertical offsets with source rectange coordinates,
as since there is no scaling being done so no recentering is
required.
