From: Namhyung Kim <namhyung@kernel.org>
The symsrc__init() overwrites dso->symtab_type as symsrc->type in dso__load_sym(). But for compressed kernel modules in the build-id cache, it should have original symtab type to be decompressed as needed.
This fixes perf annotate to show disassembly of the function properly.
