gl: avoid deadlock querying for OpenGL context

If there are two elements and threads attempting to query each other for
an OpenGL context. The locking may result in a deadlock.

We need to unlock each element's context_lock when querying another
element for the OpenGL context in order to allow any other element to
take the lock when the other element is querying for an OpenGL context.
