glx: handle spurious GLX_BufferSwapComplete events gracefully

Browse Source 
Instead of simply aborting we now print out a warning, when a spurious
GLX_BufferSwapComplete event is handled since it seems that people are
coming across the problem (perhaps due to a buggy driver) and making
apps crash in this situation is a bit extreme.
