qede: Split PF/VF ndos.
PFs and VFs share the same structure of NDOs today, and the VFs explicitly fails the ndo_xdp() callback stating it doesn't support XDP. This results in lots of: [qede_xdp:1032(enp131s2)]VFs don't support XDP ------------[ cut here ]------------ WARNING: CPU: 4 PID: 1426 at net/core/rtnetlink.c:1637 rtnl_dump_ifinfo+0x354/0x3c0 ... Call Trace: ? __alloc_skb+0x9b/0x1d0 netlink_dump+0x122/0x290 netlink_recvmsg+0x27d/0x430 sock_recvmsg+0x3d/0x50 ... As every dump request for the VF interface info would fail due to rtnl_xdp_fill() returning an error code. To resolve this, introduce a subset of the NDOs meant for the VF in a seperate structure and register that one instead for VFs, and omit the ndo_xdp initialization.
