SRIOV: During fuel deployment VF's are not enabled on a sriov enabled nic, when the nic supports less than 30 VF's

Fuel-contrail-plugin version: 4.0.1
contrail-build version: 3.0.2.0-51~ubuntu-14-04liberty

SRIOV was enabled through the Fuel GUI.

total number of VF's supported by the nic was 7.

root@node-1:~# cat /sys/class/net/eno1/device/sriov_totalvfs
7

We saw that after deployment VF's were not enabled and required configuration to enable the SRIOV were not pushed to the server after the deployment.

interface did not list any VF's after the deployment.

Loos like during the fuel provisioning by default it tries to enable 30 VF's on the nic with out checking the supported number of VF's.
