[ Upstream commit 7e334fc8003c7a38372cc98e7be6082670a47d29 ]
The VF driver also needs to create the health reporters since
VFs are also involved in firmware reset and recovery. Modify
bnxt_dl_register() and bnxt_dl_unregister() so that they can
be called by the VFs to register/unregister devlink. Only the PF
will register the devlink parameters. With devlink registered,
we can now create the health reporters on the VFs.
Fixes: 6763c779c2d8 ("bnxt_en: Add new FW devlink_health_reporter")
