Bad checking for page and limit value

[png-tech]

Division by zero for empty values.

please fix:
A limit and page can not to be zero!!

check it in setLimit and setPage.

To fix:
public function setLimit($limit)
{

•  $this->limit = max(min($limit > 0 ? $limit : 1, $this->adapter->getTotalResults()),1);
  

•   $this->limit = min($limit > 0 ? $limit : 1, $this->adapter->getTotalResults()); 
  

  ....

  public function setPage($page)
  {

•  $this->page = max(min($page > 0 ? $page : $this->getFirstPage(), $this->getLastPage()),1);
  

•   $this->page = min($page > 0 ? $page : $this->getFirstPage(), $this->getLastPage());
