Eric Dumazet 4dbb0dad8e devlink: fix netns refcount leak in devlink_nl_cmd_reload()
While preparing my patch series adding netns refcount tracking,
I spotted bugs in devlink_nl_cmd_reload()

Some error paths forgot to release a refcount on a netns.

To fix this, we can reduce the scope of get_net()/put_net()
section around the call to devlink_reload().

Fixes: ccdf07219d ("devlink: Add reload action option to devlink reload command")
Fixes: dc64cc7c63 ("devlink: Add devlink reload limit option")
