[LTP] [PATCH] lib/tst_net.sh: fix tst_set_sysctl() for non-netns setup

[Alexey Kodanev]

When we don't use netns setup, $rparam is empty in tst_set_sysctl(),
and tst_net_run() mistakenly set sysctl command to $rparam. This results
to the following error, $cmd is empty:

  bbr01 1 TINFO: timeout per run is 0h 20m 0s
  bbr01 1 TINFO: emulate congestion with packet loss 0.5%
  bbr01 1 TINFO: compare 'cubic' and 'bbr' congestion alg. results
  bbr01 1 TINFO: setting cubic
  bbr01 1 TBROK: tst_net_run: command not defined
