Reviewed by Michael Catanzaro.

* platform/graphics/gstreamer/eme/WebKitClearKeyDecryptorGStreamer.cpp:
(webkit_media_clear_key_decrypt_init): Don't re-initialize libgcrypt here
since that's already done in the WebProcess main(), and the calls here
only result in libgcrypt writing out 'Oops' warnings on stderr.
