Clean up the JTAG TAP creation handler: 

- Factor jtag_tap_init() helper out of the end of jim_newtap_cmd.
- Factor jtag_tap_free() helper out of the error case in jim_newtap_cmd.
- Invert test to improve indentation at the end of jim_newtap_cmd.
- Improve whitespace in the newly factored functions.
