[LTP] [PATCH] lib: Migrate tst_get_unused_port to new API

[Petr Vorel <pvorel@suse.cz>]

Hi,

Thanks.

I'm sorry, current implementation is wrong as it does not print port :).
I'll push it with this diff (I guess we don't need new line for port,
although that's not problematic for shell usage like this:

port=$(tst_get_unused_port ipv${TST_IPVER} stream)

Kind regards,
Petr
