growfs script: fix config-dependent errors

Browse source 
- awk sometimes formatted swapbase as floating point, which gpart
  does not accept; force int.

- Fix typo in code for checking vm.max_swap_pages.

- While here, do not set kernel env if "gpart add" fails.

- Add "gpart show" before modification to verbose output.
