cleanup_table=0

Otherwise it fails:
nft01 1 TCONF: 'nft' not found
/opt/ltp/testcases/bin/nft01.sh: line 37: [: -eq: unary operator expected

+ nit (code style comments, feel free to ignore):

1) I'd use empty variable instead of 0 (and [ "$cleanup_chain" = 1 ]),
we discuss it with previous patches.

2) I'd move TST_CNT=6 to iptables_lib.sh (if test function adds more tests, all
iptables_lib.sh uses would have to update it). Maybe all but these could be
there: TST_SETUP, TST_CLEANUP and use_iptables.

3) I'd move cleanup_table and cleanup_chain below use_iptables
(or use_iptables below, just to have all 3 variables together).

Kind regards,
Petr
