XenAPI: Fix VM live-migrate with iSCSI SR volume
With XenServer 7.0 (XCP 2.1.0), VM live migration with iSCSI volume
will fail due to no relax_xsm_sr_check in /etc/xapi.conf in Dom0.
But since XS7.0, the default value of relax_xsm_sr_check is true if
not configured in /etc/xapi.conf in Dom0.
This fix is to add checks on XCP version, if it's equal or greater
than 2.1.0, will treat relax_xsm_sr_check=true if not found in
/etc/xapi.conf

=================================
Analyze:
With XenServer 7.0 (XCP 2.1.0), "relax-xsm-sr-check=true" is the default
setting even it is not set in /etc/xapi.conf, so with XenServer 7.0 and later,
if "relax-xsm-sr-check=true" is not set, nova compute driver need use the
default value, related code:
