NetworkProcess sometimes hangs under copyDefaultCredentialForProtectionSpace

Looking at the backtrace, it's hanging forever inside the SecItem shim, waiting for a response from secItemRequest.

Looking at the SecItemShimProxy in the secItemRequest handler, it seems the only possible way a response would not be sent is if the request type was SecItemRequestData::Invalid.  That condition does an early return instead of sending back a response.

At the very least, the UIProcess should send back a response indicating "invalid request" so the NetworkProcess doesn't hang forever.
