Return false on context creation failure
Make QOpenGLContext::create() return false when the native context
could not be initialized. This way the return value and isValid()
become equivalent.
Relying on on having a non-NULL platform context is not enough, many
platforms will return a new instance even if the underlying platform
code failed to create a native context. To ensure that a platform
context is really usable, isValid() has to be checked too.
