Code Issues Proposed changes

Ensures NetApp iSCSI driver correctly compares int values for size 

The NetApp iSCSI driver needs to verify that the new size requested
during an extend operation does not exceed the max_resize of the
lun.  However, the driver was doing a >= compare against str values
of the sizes rather than the int values.  This caused the incorrect
code path to be used in certain situations.
