Zhenlei Huang 2439ae9483 mlx4, mlx5: Eliminate redundent NULL check for packet filter
mlx4 and mlx5 are Ethernet devices and ether_ifattach() does an
unconditional bpfattach(). From commit 16d878cc99 [1] and on, we
should not check ifp->if_bpf to tell us whether or not we have any bpf
peers that might be interested in receiving packets. And since commit
2b9600b449 [2], ifp->if_bpf can not be NULL even after the network
interface has been detached.

No functional change intended.

1. 16d878cc99 Fix the following bpf(4) race condition which can result in a panic
2. 2b9600b449 Add dead_bpf_if structure, that should be used as fake bpf_if during ifnet detach
