octeontx2-af: npc: Fix allmulticast skip logic for LBK and SDP VFs

When installing the allmulticast NPC rule, rvu_npc_install_allmulti_entry()
should skip LBK and SDP VFs (only CGX PF/VF may add the entry).  The
code combined is_lbk_vf() and is_sdp_vf() with logical AND, which is
never true for a single pcifunc, so the intended early return never ran.

Use logical OR instead.
