igb: Enable SR-IOV after reinit
Enabling SR-IOV causes the virtual functions to make requests to the PF via the mailbox. Notably, E1000_VF_RESET request will happen during the initialization of the VF. However, unless the reinit is done, the VMMB interrupt, which delivers mailbox interrupt from VF to PF will be kept masked and such requests will be silently ignored. Enable SR-IOV at the very end of the procedure to configure the device for SR-IOV so that the PF is configured properly for SR-IOV when a VF is activated.
