Improve performance of CheckValidity.
This patch improves performance of CheckValidity() by removing calls to
leveldb::DB::Get() from loops.
As a result the performance improved by 1.92x on Yoshi, for a testing account
with a lot of files.
Note, that base::hash_map is used, as its much faster in this case. Using
std::map gave only 1.39x performance gain over the former solution.
TEST=unit_tests: *ResourceMetadataStorageTest*, also tested manually.
