Added a check for a non-zero MIP before doing retries.

This change fixes an uncommanded-motion bug that occurs under the following conditions:
1. A motor is moved from outside EPICS, making its EPICS readback position out-of-sync.
2. The motor is controlled by a controller that supports motor groups (like the Newport XPS).
3. The motor belongs to a motor group.
4. A status update is requested for any of the other motors in the motor group.
