intel: Fix segfault in intel_texsubimage_tiled_memcpy
did fix the segfault, but introduced yet another bug. From Anholt: """You
need to still test format/type, because that's the incoming format (e.g.
GL_RGBA/GL_FLOAT) that you're trying to memcpy."""
This patch re-introduces the checks on the incoming format and type.
Note: This is a candidate for the 9.0 branch.
