st/mesa: an incomplete texture may have a zero-size first image
Fixes a regression introduced by commit 42624ea83 which triggered
an assertion in
dEQP-GLES2.functional.texture.completeness.cube.not_positive_level_0
While stImage must have a non-zero size as verified by the caller, we also
look at the size of the base image in an attempt to make a better guess at
the level0 size (this is important when the base image size is odd). However,
the base image may have a zero size even when it exists.
