[Cogl] [PATCH] context: Simplify _cogl_context_get_default

[Robert Bragg]

From: Robert Bragg <robert at linux.intel.com>

Since the 2.0 api requires developers to explicitly create a CoglContext
we no longer need to be able to create a context lazily in
_cogl_context_get_default() so the function can simply be reduced to an
assertion that a context has been created and return the file scope
_cogl_context pointer.
