sqlsrv_fetch_array() function returns an array when data found,
null when no data or false on error. So we need to change null to false only.

[ticket/12704] Improve the load time information in the footer when enabled
PR #2570 has added new constant to display load time information without
debug mode is being on (https://tracker.phpbb.com/browse/PHPBB3-12687).
This patch expands the total load time info with SQL/PHP load times,
while hiding the additional info with <abbr> element.
