perf dso: Fix symtab_type for kmod compression

During the rework of the dso structure in patch ee756ef7 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.

Fixes: ee756ef7 ("perf dso: Add reference count checking and accessor functions")
