Bug 8586: Alarm raised due to stale stats polling

Root cause - When port stats polling is enabled, first poll returns
old data (Rx bytes and Dropped bytes) when QoS alert was not enabled.
Alert may get logged if stale stats has dropped % > threshold value

Fix - Alert should not be logged based on first poll data. Use first poll data
to set the baseline counts and raise alert on subsequent polls based on the delta
of counts between the polls.
