[dx65] mipmap change

[Ann and Jason Edmeades]

The following is not a result of actually seeing a problem, but
something I noticed while debugging another problem. If texture 1 has
mip levels of 10 and is replaced by texture 2 with mip levels 1, should
texture 1 need to be bound back in then we should reset the max levels
back to 10. I also took the setting out of the for loop (we dont need to
issue it 'levels' times) as well as moving the setting of the dirty flag
outside the for loop.

Changelog
Ensure MIPMAP levels is reset when rebinding an existing texture to a
texture unit.
