qed: Don't ignore devlink allocation failures
[ Upstream commit e6a54d6f221301347aaf9d83bb1f23129325c1c5 ]
devlink is a software interface that doesn't depend on any hardware
capabilities. The failure in SW means memory issues, wrong parameters,
programmer error e.t.c.
Like any other such interface in the kernel, the returned status of
devlink APIs should be checked and propagated further and not ignored.
Fixes: 755f982bb1ff ("qed/qede: make devlink survive recovery")
