perf symbols: Keep DSO->symtab_type after decompress

Browse source 
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.
