devlink: Add device lock assert in reload operation
Add an assert to verify that the device lock is always held throughout
reload operations.
Tested the following flows with netdevsim and mlxsw while lockdep is
enabled:
netdevsim:
# echo "10 1" > /sys/bus/netdevsim/new_device
# devlink dev reload netdevsim/netdevsim10
# ip netns add bla
# devlink dev reload netdevsim/netdevsim10 netns bla
# ip netns del bla
# echo 10 > /sys/bus/netdevsim/del_device
mlxsw:
# devlink dev reload pci/0000:01:00.0
# ip netns add bla
# devlink dev reload pci/0000:01:00.0 netns bla
# ip netns del bla
# echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
# echo 1 > /sys/bus/pci/rescan
