net/i40e: re-program promiscuous mode on VF interface

During a kernel PF reset, this event is propagated to the VF.
The DPDK VF PMD will execute the reset task before the PF is done
with his. This results in the admin queue message not being responded
to leaving the port in "promiscuous" mode.

This patch makes sure the promiscuous mode is configured independently
of the current admin state.
