mesa: Skip texstore for 0-sized texture data.
The intel driver (and gallium, it looks like, though it doesn't use
these texstore functions at this point) doesn't bother making storage
for textures with 0 width, height, or depth. This avoids them having
to deal with returning a mapping for that nonexistent data.
Fixes assertion failures with an upcoming intel driver change.
