Patch to fix problem above

There is a conflict between the definitions of struct nv50_miptree and
nv[1-4]0_miptree + nv04_miptree. Note that nv50_miptree starts with struct
nouveau_miptree. Sometimes pipe_textures are cast to nouveau_miptree, although
the pt was part of a nv40_miptree (for example). This results in the bo field
pointing to an incorrect location, resulting in segfaults, etc. The patch does
not change the nv50 driver (or shouldn't). I have tested it on 7300 GT only. 

Best Wishes,

Bob Gleitsmann
