mesa/main: Prevent sefgault on glGetIntegerv(GL_ATOMIC_COUNTER_BUFFER_BINDING).
A recent ApiTrace change, that tries to dump more buffer state
causes Mesa from my distro (10.1.4) to segfaults here.
I haven't actually confirm this fixes it (I can't repro on master),
but it seems a good idea to be defensive here anyway.
