vnic: apply BPF tap before passing packet to hardware
Previously we passed tx packets to hardware via nicvf_tx_mbuf_locked and then to the BPF tap, with a possibly invalid mbuf which would result in a panic. PR: 223600 Discussed with: bz MFC after: 1 week Sponsored by: The FreeBSD Foundation, Packet.net (hardware)
