    ms/perf dso: Fix symtab_type for kmod compression
    
    During the rework of the dso structure in patch ee756ef7491eafd an
    increment was forgotten for the symtab_type in case the data for
    the kernel module are compressed. This affects the probing of the
    kernel modules, which fails if the data are not already cached.
    
    Increment the value of the symtab_type to its compressed variant so the
    data could be recovered successfully.
