glxproxy: Fix an obvious thinko in QueryExtensionsString
gcc 5.1 throws a rather amusing warning here:
glxcmdsswap.c: In function ‘__glXSwapQueryExtensionsString’:
glxcmdsswap.c:439:1: warning: function might be candidate for attribute
‘noreturn’ [-Wsuggest-attribute=noreturn]
__glXSwapQueryExtensionsString(__GLXclientState * cl, GLbyte * pc)
This is entirely accurate, albeit curiously phrased: swapping some bits
hanging off the end of a null pointer will make Xdmx crash, so from the
perspective of code generation the function will indeed not return.
