st/mesa: check if _mesa_create_context() returns NULL
In some cases _mesa_create_context() can return NULL an in the mesa state tracker, we do not concider the case, which may cause issues within st_create_context_priv() This patch adds a simple check (similar to the one in the dri drivers) Signed-off-by: Emil Velikov <[email protected]> Signed-off-by: Brian Paul <[email protected]>
