GL_TEXTURE_2D_MULTISAMPLE and GL_TEXTURE_2D_MULTISAMPLE_ARRAY targets
don't allow filtering state to be set, but the default state fails the
completeness check for integer formats.
We still care about other reasons the texture might be considered
incomplete though, so can't skip this entirely like GL_TEXTURE_BUFFER.
