mesa: fix invalid target error handling for teximage

This commit moves the target check before using _mesa_get_current_tex_object
to fix a "Mesa implementation error: bad target in _mesa_get_current_tex_object()"
error.

Fixes: 9dd1f7cec01 ("mesa: pass gl_texture_object as arg to not depend on state")
