[PATCH] ipw2200: Fix rf_kill is activated after mode change with 'disable=1'

When loading the ipw2200 module with disabled=1, rf_kill is activated after
every mode change. This is caused by ipw_sw_reset() is called when a mode
is changed. The patch fixed the problem by distinguishing the purposes with
the 'option' paramenter.
