Change "blocks" to "block" for db_query because of table name change

The blocks table no longer exists in D7. It is now called block. Error shown:

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'xyz.blocks' doesn't exist: SELECT title FROM {blocks} WHERE module='featured_content' AND delta=:delta; Array ( [:delta] => 2 ) in featured_content_get_block_title() (line 1970 of /var/www/xyz/sites/all/modules/contrib/featured_content/featured_content.module).

Also need to fix the:

$row = $results[0];

to be:

$row = $result->fetchObject();
