[PATCH nft v3 3/6] tests/py: simplify use of globals

["Pablo M. Bermudo Garay" <pablombg@gmail.com>]

The script made a messy use of globals, these was sometimes accessed
directly and passed as parameter in other cases.

Since is not expected having to deal with threads in the script, now the
globals are always accessed directly for the sake of simplicity.
