codec/progressive: Fix a memory leak

When checking whether tiles and updatedTileIndices are both non-NULL,
one of them might be NULL, while the other struct member might not
be NULL and progressive_surface_context_new() leaks then the non-NULL
struct member.

Fix this by freeing both struct members, when aborting in
progressive_surface_context_new().
free() will take no action on pointers that are NULL, so no additional
check is needed.
