Namhyung Kim 8e67b7258e perf symbols: Protect dso cache tree using dso->lock 
The dso cache is accessed during dwarf callchain unwind and it might be
processed concurrently.  Protect it under dso->lock.

Note that it doesn't protect dso_cache__find().  I think it's safe to
access to the cache tree without the lock since we don't delete nodes.

It it missed an existing node due to rotation, it'll find it during
dso_cache__insert() anyway.
