Parav Pandit dac7c08f98 devlink: Fix list access without lock while reading region 
While finding the devlink device during region reading,
devlink device list is accessed and devlink device is
returned without holding a lock. This could lead to use-after-free
accesses.

While at it, add lockdep assert to ensure that all future callers hold
the lock when calling devlink_get_from_attrs().

Fixes: 4e54795a27f5 ("devlink: Add support for region snapshot read command")
