mesa: Validate target before resolving tex obj in glTex(ture)SubImageXD

Browse Source 
Currently, glTexSubImageXD attempt to resolve the texture object
(by calling _mesa_get_current_tex_object()) before validating the given
target. However, that method explicitly states that target must have been
validated before calling it, so it never returns a user error.

The target validation occurs later when texsubimage_error_check() is called.

This patch reorganizes target validation, taking it out from the error check
function and into a point before the texture object is resolved.
