[PATCH iproute2] devlink: Call dl_free in early exit case

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

Prior to parsing command options, the devlink tool allocates memory
to store results. In case of early exit (wrong parameters or version
check), this memory wasn't freed.
