During an upgrade from Rel. 7 to Rel. 8 the upgrade-activate failed
and after some time it was executed again. In the second
upgrade-activate execution, the update_platform_nfs_ip_references
was called again, but it failed because plat_nfs_ip was empty.
It happened because this function was already executed once and at
the end of it the plat_nfs_ip is removed from system.yaml
So if this variable is empty, it means that upgrade-activate was
called again and there is nothing to do.
Test plan
PASS AIO-DX upgrade from Rel 7 to 8
PASS manual change in this function changing the plat_nfs_ip
value to:
$plat_nfs_ip = undef
$plat_nfs_ip = ''
And executing the upgrade-activate and confirm that
commands were not executed
