coccinelle warnings: (new ones prefixed by >>)

>> drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd.c:886:2-7: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values.

Please review and possibly fold the followup patch.
