zebra: Fixing Comments in MLAG Read scheduling Events

Browse Source 
Zebra MLAG is using "t_read" for multiple tasks, such as

1. For opening Communication channel with MLAG
2. In case conncetion fails, same event is used for retries
3. after the connection establishment, same event is used to
   read the data from MLAG

since all these taks will never schedule together, this will not
cause any issues.
