ixgbe: remove timer reset to 0 on timeout
The VF mailbox polling for acks and messages would reset the timer to zero on a timeout. Under heavy load a timeout may actually occur without being the result of an error and when this occurs it is not practical to perform a full VF driver reset on every message timeout. Instead, just return an error (which is already done) and the VF driver will have an opportunity to retry the operation.
