Subject: [PATCH AUTOSEL 6.2 51/53] devlink: health: Fix nla_nest_end in error flow

From: Moshe Shemesh <moshe@...dia.com>

[ Upstream commit bfd4e6a5dbbc12f77620602e764ac940ccb159de ]

devlink_nl_health_reporter_fill() error flow calls nla_nest_end(). Fix
it to call nla_nest_cancel() instead.

Note the bug is harmless as genlmsg_cancel() cancel the entire message,
so no fixes tag added.
