glx: Undo memory allocation checking damage.
This partially reverts commit d41f5396f3cb619729021390c273f838d92f11fb.
That untested commit broke the tex-skipped-unit piglit test and the
arbvparray Mesa demo when run with indirect GLX.
state->array_state is used during initialization, so its assignment cannot be
moved to the end of the function.
The backtrace looked like:
Program received signal SIGSEGV, Segmentation fault.
