Revert "Don't reuse scratch textures when texsub image banned for FBO textures"

This reverts commit 2a88456c15.

Reason for revert: speculative -- fix marshmellow gl on chrome roll?

Original change's description:
> Don't reuse scratch textures when texsub image banned for FBO textures
>
> If writePixels uses a scratch surface it will likely bind it to a FBO.
> If this workaround is in play that texture then becomes "poisoned" as
> a temp surface for a future writePixels(). However, our caching
> mechanism will still find it and we'll incur an extra recursion in
> writePixels to allocate a new texture that has never been bound to a
> FBO. This pattern can repeat itself with increasing recursion depth
> until the cache budget has been reached and we start purging the
> "poisoned" textures.
>
> Disallowing reuse of scratch textures avoids this issue.
