target algo: do not write reg_param if direction is PARAM_IN
Without this change xxx_start_algorithm() writes all register
parameters no matter of their direction. It usually results
in writing of uninitialized reg_params[].value - possibly
reported by valgrind.
While on it fix the wrong parameter direction in
kinetis_disable_wdog_algo(). This bug did not have any
impact because of unconditional write of reg_params.
