[PATCH 4/5] wined3d: Drop redundant check for instanced rendering from drawStridedFast.

We need GL_ARB_instanced_arrays to be able to take the fastest path and
that's already checked in draw_primitive.
Note that GL_ARB_instanced_arrays provides glDrawElementsInstanced if
GL_ARB_draw_instanced is not supported so we don't need to explicitly
check for the latter.
