glx: Be more paranoid about variable-length requests [CVE-2014-8093 1/6] (v2)
If the size computation routine returns -1 we should just reject the
request outright. Clamping it to zero could give an attacker the
opportunity to also mangle cmdlen in such a way that the subsequent
length check passes, and the request would get executed, thus passing
data we wanted to reject to the renderer.
v3: backport to nx-libs 3.6.x (Mike DePaulo)
v2: backport to RHEL5 - fix swap paths
