Windows: Checksum server lists on Volume Errors

Windows: Checksum server lists on Volume Errors

For VMOVED, VNOVOL and VOFFLINE checksum the server lists for
the current volume.  If the server list changes as a result of
the forced volume location update, do not set the updated flag
which prevents subsequent volume location updates for the current
cm_req object.

This combined with the previous patchset to filter volume locations
based upon the VLSF_NEWREPSITE flag will avoid outages during
vos release operations.
