gen7: fix GPU hang on WebGL texture-size test
When rendering to a texture with BaseLevel set, the miptree may be laid
out such that BaseLevel is in level 0 of the miptree (to avoid wasting
memory on unused levels between 0 and BaseLevel-1). In that case, we
have to shift our render target's level down to the appropriate level of
the smaller miptree.
The WebGL test in combination with a meta code relating to
glGenerateMipmap also triggered a similar failure scenario.
This GPU hang regression was introduced by c754f7a8.
