[support] can't clean $user->data in DB

[Ivan Sergio Borgonovo]

Not that it really matter to make things work... but I injected some
fields in the user edit form:

$form['block']['field'] = Array(
	'#title' => t('Page'),
	'#type' => 'textfield',
	'#maxlength' => 10,
	'#size' => 11,
	'#default_value' => $edit['field'],
);


I cleared them in the update/insert hook_user

$edit['field']=NULL;

but I still get b:0; in the data field of the DB.
