fixes segfaults on Evergreen

With latest git master I see a lot of segfaults with Evergreen GPU. Even with the simple redbook hello program.

Program received signal SIGSEGV, Segmentation fault. 0xb76eb25f in evergreenSendDB (ctx=0x807df78, atom=0x807aca8) at evergreen_chip.c:956 956 zheight = rrb->base.Height;

It's trying to dereference a null pointer (rrb) here. Proposed fix attached.
