Fix a potential segfault in GpuVideoDecoder

Fix a potential segfault in GpuVideoDecoder

It's possible that NotifyError() is called between Initialize() and
CompleteInitialization() which would previously result in a null pointer
dereference. Now initialization is completed with an error.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
