fix: mm, vmscan signatures changed in linux 6.7.0-rc1

See upstream commit:

    commit 3dfbb555c98ac55b9d911f9af0e35014b445fb41

        mm, vmscan: remove ISOLATE_UNMAPPED

        This isolate_mode_t flag is effectively unused since 89f6c88a6ab4 ("mm:
        __isolate_lru_page_prepare() in isolate_migratepages_block()") as
        sc->may_unmap is now checked directly (and only node_reclaim has a mode
        that sets it to 0).  The last remaining place is mm_vmscan_lru_isolate
        tracepoint for the isolate_mode parameter.  That one was mainly used to
        indicate the active/inactive mode, which the trace-vmscan-postprocess.pl
        script consumed, but that got silently broken.  After fixing the script by
        the previous patch, it does not need the isolate_mode anymore.  So just
        remove the parameter and with that the whole ISOLATE_UNMAPPED flag.
