Cleanup nuisance DVLOG calls in safe_browsing_database.cc.

Was doing a cleanup on filename storage, and the DVLOGs annoyed me.

File chrome/browser/safe_browsing/safe_browsing_database.cc (right):

https://codereview.chromium.org/344513003/diff/1/chrome/browser/safe_browsing...
chrome/browser/safe_browsing/safe_browsing_database.cc:776: << " hash:" <<
base::HexEncode(hash.data(), hash.size());
I did not remove this one because it looks complicated enough that someone must
have used it once upon a time.  But I wouldn't need much encouragement to remove
it.

https://codereview.chromium.org/344513003/diff/1/chrome/browser/safe_browsing...
chrome/browser/safe_browsing/safe_browsing_database.cc:1535: << " hashed_ip:" <<
base::HexEncode(hashed_ip_prefix.data(),
Likewise this one.
