hsr: Handle failures in module init
A failure during registration of the netdev notifier was not handled at all. A failure during netlink initialization did not unregister the netdev notifier. Handle failures of netdev notifier registration and netlink initialization. Both functions should only return negative values on failure and thereby lead to the hsr module not being loaded.
