  [ORC] Avoid invalidating iterators in EHFrameRegistrationPlugin.

In EHFrameRegistrationPlugin::notifyTransferringResources if SrcKey had
eh-frames associated but DstKey did not we would create a new entry for DskKey,
invalidating the iterator for SrcKey in the process. This commit fixes that by
removing SrcKey first in this case.
