devlink: find snapshot in devlink_nl_cmd_region_read_dumpit

The snapshot pointer is obtained inside of the function
devlink_nl_region_read_snapshot_fill. Simplify this function by locating
the snapshot upfront in devlink_nl_cmd_region_read_dumpit instead. This
aligns with how other netlink attributes are handled, and allows us to
exit slightly earlier if an invalid snapshot ID is provided.

It also allows us to pass the snapshot pointer directly to the
devlink_nl_region_read_snapshot_fill, and remove the now unused attrs
parameter.
