BUG#24860 (Incorrect SLAVE_TRANSACTION_RETRIES code can result in slave stuck):

Browse Source 
If a temporary error occured inside a group on an event that was not the first
event of the group, the slave could get stuck because the retry counter is reset
whenever an event was executed successfully.

This patch only reset the retry counter when an entire group has been successfully
executed, or failed with a non-transient error.
