profileinfo: Suppress frivolous warning about usort callback

When sorting the profile output by a column (e.g. ms/call) the
following error appears:

> PHP Warning:
> usort(): Array was modified by the user comparison function at profileinfo.php:439

This is a known bug in PHP where usage of certain debug features
can cause usort() to detect reference count change and wrongly
claim that the object was changed.
