r345742 replaced fusefs's fufh array with a fufh list. But it left a few array idioms in place. This commit replaces those idioms with more efficient list idioms. One location is in fuse_filehandle_close, which now takes a pointer argument. Three other locations are places that had to loop over all of a vnode's fuse filehandles.
