[PATCH] prio-tree: remove function prototype inside function

[PATCH] prio-tree: remove function prototype inside function

I had a problem when compiling a 2.6 kernel with gcc 3.5 CVS.  The
prototype for prio_tree_remove in mm/prio_tree.c is inside another
function.  gcc 3.5 gets upset and removes the function completely.
Apparently this isnt valid C, so lets fix it up.
