mesa: reset the source packing when creating temp transfer image
Commit 4b249d2e (mesa: Handle transferOps in texstore_rgba) introduced proper transferops handling, but in updating the source to the newly allocated temporary image neglected to reset the source packing. Set it to the default which should be appropriate for the floats used.
