[Intel-gfx] [PATCH] intel: Allocate swrast buffer (#54782)

[Frederic Plourde]

From: Tomeu Vizoso <tomeu.vizoso at collabora.com>

When i915 driver decides to fallback to software, the texture's Map
gets replaced by its Buffer attribute, which is NULL because the 
texture hasn't been allocated by swrast yet.

The attached patch makes sure that the image buffer for the texture 
gets allocated
