[LTP] [PATCH 3/9] tst_net.sh: Remove unneeded $_tst_net_parse_variables

[Petr Vorel]

$_tst_net_parse_variables guarder (originally introduced as
$TST_PARSE_VARIABLES in 9aab3ffd55) was not needed any more since
a93c34f914 which introduced $TST_LIB_NET_LOADED guarder at the top of
the file.

was used as a guarder to protect running
configuration in case tst_net.sh was loaded more times.

Fixes: a93c34f914 ("tst_net.sh: Introduce TST_LIB_NET_LOADED")
