vc4: fix vc4_resource_from_handle() stride calculation
The expected stride calculation is completely wrong. It should
ultimately be multiplying cpp and width rather than dividing. The width
also needs to be aligned to the tiling width first before converting to
stride bytes.
The whole stride check here is possibly pointless. Any buffers which
were allocated outside of vc4 may have strides with larger alignment
requirements.
