mesa: Fix FB blitting in case of zero size src or dst rect
Framebuffer blitting operation should be skipped if any of the
dimensions (width/height) of src/dst rect is zero.
V2: Move the dimension check after error checking in _mesa_BlitFramebuffer.
Fixes: fbblit(negative.nullblit.zeroSize) in Intel oglconform

Note: Candidate for all the stable branches.
