meta: Fix invalid PBO access from DrawPixels when trying to just alloc.

This whole reuse of buffers (TexSubImage instead of TexImage, SubData
instead of Data) is bad for hardware drivers, but it's even worse when
we accidentally try to access the 2x2 PBO to fill the new 16x16 texture
we're creating, producing GL errors.

Fixes piglit pbo-drawpixels.  Bug #14163.
