Reviewed by Dan Glastonbury.

Remove m_needsUpdate. It controlled the
`renderBox->contentChanged(CanvasChanged)` call when the context was
created during reshape, only the first time after a context creation.

Initial creation for HTMLCanvasElement will call contentChanged
explicitly.

Upon restoring lost context, this is called after successful restore.
