Bug 10838: (follow-up) silence another warn

To test:

[1] In the staff interface, enter nothing in the patron search box
    and hit the search button.
[2] Note the errors in the logs concerning an uninitialized $count
    variable.
[3] Apply the patch and repeat step 1.  Note that this time, no
    warnings are logged.
