Make sure network interfaces on an N3000 FPGA are enabled for SR-IOV only after the device is reset

During backup/restore it was found that multiple unlock attempts
failed with the following error message:
"Expecting number of interface sriov_numvfs=8. Please wait a few
 minutes for inventory update and retry host-unlock"

This happens because the FPGA reset affects the NIC ports attached to
it removing the SR-IOV configuration done before.

This commit adds a sriov-enable dependency to N3000 FPGA reset to make
sure that SR-IOV is re-configured after the reset.

Test Plan:
PASS: AIO-SX: change numvfs, unlock and check puppet logs
