Subject: [PATCH net 4/4] ice: register devlink prior to creating health reporters

From: Przemek Kitszel <przemyslaw.kitszel@...el.com>

ice_health_init() was introduced in the commit 2a82874a3b7b ("ice: add
Tx hang devlink health reporter"). The call to it should have been put
after ice_devlink_register(). It went unnoticed until next reporter by
Konrad, which receives events from FW. FW is reporting all events, also
from prior driver load, and thus it is not unlikely to have something
at the very beginning. And that results in a splat:
[   24.455950]  ? devlink_recover_notify.constprop.0+0x198/0x1b0
[   24.455973]  devlink_health_report+0x5d/0x2a0
[   24.455976]  ? __pfx_ice_health_status_lookup_compare+0x10/0x10 [ice]
[   24.456044]  ice_process_health_status_event+0x1b7/0x200 [ice]

Do the analogous thing for deinit patch.
