[ 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.
