net: hns3: fix kernel crash when devlink reload during initialization

net: hns3: fix kernel crash when devlink reload during initialization
[ Upstream commit 35d92abfbad88cf947c010baf34b075e40566095 ]
The devlink reload process will access the hardware resources,
but the register operation is done before the hardware is initialized.
So, processing the devlink reload during initialization may lead to kernel
crash.
This patch fixes this by registering the devlink after
hardware initialization.

There is a memory barrier in followed case. When set the port down,
hclgevf_set_timmer will set DOWN in state. Meanwhile, the service task has
different behaviour based on whether the state is DOWN. Thus, to make sure
service task see DOWN, use smp_mb__after_atomic after calling set_bit().

net: hns3: use appropriate barrier function after setting a bit value
[ Upstream commit 094c281228529d333458208fd02fcac3b139d93b ]
There is a memory barrier in followed case. When set the port down,
hclgevf_set_timmer will set DOWN in state. Meanwhile, the service task has
different behaviour based on whether the state is DOWN. Thus, to make sure
service task see DOWN, use smp_mb__after_atomic after calling set_bit().

net: hns3: fix kernel crash when devlink reload during initialization
[ Upstream commit 35d92abfbad88cf947c010baf34b075e40566095 ]
The devlink reload process will access the hardware resources,
but the register operation is done before the hardware is initialized.
So, processing the devlink reload during initialization may lead to kernel
crash.
This patch fixes this by registering the devlink after
hardware initialization.
