Felix Maurer 69f9f55891 hsr: Handle failures in module init
[ Upstream commit 3cf28cd492 ]

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.
