Either
A) Restart the management agents on the ESXi host as per http://kb.vmware.com/kb/1003490
or
B) Remove the VM from Inventory and re-add it by browsing to the VMX file on the datastore
or
C) Reload the VM from the ESXi shell as explained here http://kb.vmware.com/kb/1026043
Any of the above should fix VM config inconsistencies between vCenter and hosts like you're seeing. A vMotion might work too, but I'm not entirely sure.
