quadtree: Fix compiler warnings

quadtree.c:370: warning: unused variable ‘ret’

Trivial remove

quadtree.c: In function ‘quadtree_find_nearest’:
quadtree.c:369: warning: ‘distance’ may be used uninitialized in this function

This variable will not be used uninitialized, but the compiler warning
is trivial to fix with simply initializing the variable with zero.
