i915: Initialize swrast_texture_image structure fields.
Commit 980f6f1 (mesa: move gl_texture_image::Width/Height/DepthScale
fields to swrast) moved the initialization of the Width, Height, and
DepthScale fields to _swrast_alloc_texture_image_buffer(). However,
i915 doesn't call this function because it performs its own buffer
allocation. As a result, the Width, Height, and DepthScale fields
weren't getting initialized properly, and some operations requiring
swrast would fail.
This patch ensures that Width, Height, and DepthScale are properly
initialized by separating the code that sets them into a new function,
_swrast_init_texture_image(), which is called by
intel_alloc_texture_image_buffer() as well as
_swrast_alloc_texture_image_buffer(). It also moves the
initialization of _IsPowerOfTwo into this function.
It passes on pineview now.
Verified with Mesa master commit 33202b4876a88b6f54ca7022eadd2875a2d3508a.
