Review Comment:
   The last argument of `sendDhtRequests` method is `boolean sndRes`. It 
controls whether backups, after processing GridDhtAtomicUpdateRequest, will 
send a response to the `near` node with `hasResult` flag set to true or false. 
If `near` node receives responses from all backups with 
`GridDhtAtomicNearResponse#hasResult`set to true - it can complete cache 
operation without waiting for a response from the primary node 
(GridNearAtomicUpdateFuture#onDhtResponse).
   
   Problem this PR is intended to solve - `near` node revceives responses from 
all backups and completes `putAll` operation before primary node sends 
GridDhtAtomicNearResponse message with a list of entries that it failed to 
process. `near` node receives no information from backup nodes that primary 
node failed to process some entries but completes putAll operation 
successfully. Near node must rise exception or successfully insert all 
inserting entries.
   
   So `!(readersOnlyNodes || hasPrimaryUpdErrors)` makes `near node` not to 
complete `putAll` operation even if it receives all responses from backup 
nodes, but wait for the responce from primary node (it contains entries which 
processing is failed).
