eal/windows alarm APIs rte_eal_alarm_set and rte_eal_alarm_cancel
did not check parameters to fail fast for invalid parameters, which
caught by DPDK UT alarm_autotest.

Enforce eal/windows alarm APIs parameter check to fail fast for
invalid parameters.

Fixes: f4cbdbc7fbd2 ("eal/windows: implement alarm API")

V2 changes:
    - Remove API parameter check on arbitrary 'us' range
    - Do explicit NULL cb_fn check
