add device state check define to avoid use of internal struct fileds in app level

[ayedm1]

add a define

#define UX_SLAVE_DEVICE_CHECK_STATE(state)                                                        \
  (_ux_system_slave->ux_system_slave_device.ux_slave_device_state & (state)) ? UX_TRUE : UX_FALSE \

instead of testing device state at applicative level

     UX_SLAVE_DEVICE *device;
     device = &_ux_system_slave->ux_system_slave_device;

    /* Check if the device state already configured */
    if ((device->ux_slave_device_state == UX_DEVICE_CONFIGURED) && (hid_mouse != UX_NULL))
    {
    }

we can do that :

      if ((UX_SLAVE_DEVICE_CHECK_STATE(UX_DEVICE_CONFIGURED)) && (hid_mouse != UX_NULL))
      {
      }
