cxgb4: Fix for SR-IOV VF initialization
Commit 35b1de5 ("rdma/cxgb4: Fixes cxgb4 probe failure in VM when PF is exposed
through PCI Passthrough") introduced a regression, where VF failed to
initialize for Physical function 0 to Physical Function 3. In the above
commit, we removed the code which used to enable sriov for PF0 to PF3. Now
adding it back to get sriov working.
V2:
Removed SRIOV loop for PF[0..3] to instantiate the VF's as per David Miller's
comment
