coccinelle: ifnullfree: various cleanups
Adjust tests to compare against NULL, to match cases that explicitly make that comparison. Remove removal and re-addition of freeing functions. Add position variable on usb_free_urb in the non-patch case. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Michal Marek <mmarek@suse.cz>
