Workaround for NVIDIA

This may be due to a driver error. With Assassins Creed and query buffer
objects it is seems to be easy to make the gpu unhappy. This error shows up in
dmesg:

Xid (PCI:0000:01:00): 32, Channel ID 00000023 intr 00040000

Avoiding concurrent writes to the same buffer object appears to help, but it is
possible that it is just reducing the chance of error instead of eliminating
it.

This patch reverts to using a random value to indicate an invalid value. It
also uses glBufferStorage to initialize the buffer and eliminates any CPU
writes to the buffer.
