net/hsr: Fix NULL pointer dereference on incomplete hsr_newlink() params. If none of the slave interfaces are specified, struct nlattr *data[] may be NULL. Make sure to check for that. While I'm at it, fix the horrible error messages displayed when only one of the slave interfaces isn't specified. Signed-off-by: Arvid Brodin <arvid.brodin@alten.se> Signed-off-by: David S.
