[nautilus/gnome-2-28] Correctly update the request counters

[Alexander Larsson <alexl src gnome org>]

commit 908328c77207b47ac4a43af09422d641b0240331
Author: Alexander Larsson <alexl redhat com>
Date:   Tue Nov 17 10:01:58 2009 +0100

    Correctly update the request counters
    
    The request counters weren't updated by nautilus_directory_add_file_monitors
    and nautilus_directory_remove_file_monitors. This can cause a number of weird
    problems, including those described in bug #598931.
    
    This checkin fixes this, and fixes bug #598931.
    (cherry picked from commit e487552287e5970dbbb39199b55026f2788bb42b)
