drm/xe/oa: Ensure that polled read returns latest data
In polled mode, user calls poll() for read data to be available before
performing a read(). In the duration between these 2 calls, there may be
new data available in the OA buffer. To ensure user reads all available
data, check for latest data in the OA buffer in polled read.
