fixes bug where setting state=absent in nxos_nxapi is not idempotent (#4984)

When setting state=absent the nxos_nxapi module would always try to remove
the configuration regardless of the current state of the device.  This will
fix that problem.

This also updates the docstring to correctly reflect https as default=no
