[intel] Fix and reenable (software) SGIS_generate_mipmap

The core problem was that _mesa_generate_mipmap was not respecting RowStride
of the source image.  Additionally, the intel private data associated with the
images (level and face) was not being initialized for the
_mesa_generate_mipmap-generated images.
