Subject: cmd_sb_occ_show doesn't call dl_put_opts

Hey Jiri,

I noticed while looking at implementing policy checking support in
devlink that the cmd_sb_occ_show calls dl_argv_parse but then doesn't
call dl_put_opts, so it doesn't seem to be sending any of the attributes
down to the kernel.

I am guessing this is not done on purpose, and is just an oversight,
caused by needing to send two different netlink messages.

It looks like the code could use a dl_argc check to determine whether to
use NLM_F_DUMP and call dl_put_opts to ensure the netlink attributes get
added..?

Thanks,
Jake
