Galleries listing empty in og galleries admin

Hi:

I had a the following problem:
A user with administer og galleries permissions goes to galleries (node/xx/galleries) and always gets an "No galleries available" message.
Only user 0 can see this list.

After some research, i've found that the problem is in og_galleries_db_rewrite_sql
We use $user->og_groups but it's possible that this was not initialized at that moment (for example in the admin page). So we need to do an user_load...

This is the change I propose to db_rewrite hook

function og_galleries_db_rewrite_sql($query, $table, $field) {
  if (!user_access('administer site configuration') && ($field =='vid' || $field =='tid')) {
    global $user;
    // we have to perform a load in order to assure that the $user->og_groups bits are present.
    if ($user->uid) {
      $user = user_load(array('uid' => $user->uid));
    }
    else {
      $user->og_groups = array();
    }
    
    $op = (arg(0) == 'node' && (arg(1) == 'add' || arg(2) == 'edit')) ? 'create' : 'list';

This solved the problem for me.

I've attached a patch for your review.
