    xfrm: remove input2 indirection from xfrm_mode · b3284df1

    No external dependencies on any module, place this in the core.
    Increase is about 1800 byte for xfrm_input.o.
    
    The beet helpers get added to internal header, as they can be reused
    from xfrm_output.c in the next patch (kernel contains several
    copies of them in the xfrm{4,6}_mode_beet.c files).
    
    Before:
       text    data     bss     dec filename

    After:
       text    data     bss     dec filename

    v2: pass inner_mode to xfrm_inner_mode_encap_remove to fix
