[dconf] Remove unused 'error' variable

[Ryan Lortie <ryanl src gnome org>]

commit 6d74d372de6c68774edcccb1727221c59475b0d3

    Remove unused 'error' variable
    
    We never consumed the value, and then we reused it, causing warnings
    about uninitialised error variables.  Just remove it altogether.
    
    Caught by Matthias.
