Clean up the code in rtw_pwr_wakeup that sets pwrpriv->ips_deny_time.
Make ips_deny_time an unsigned long, this type is used by the kernel
functions that process jiffies.
Remove the temporary variable ips_deffer_ms and use
RTW_PWR_STATE_CHK_INTERVAL directly.
There's no need to set ips_deny_time twice, it's sufficient to set it at
the end of rtw_pwr_wakeup.
Use time_before to check if ips_deny_time should be updated.
We can now remove rtw_ms_to_systime, this function is not used any more.
