i965: fix segfault on low memory conditions
When out of memory (in at least one case, triggered by a longrunning memory leak), this code will segfault and crash. By checking for the out-of-memory condition, the system can continue, and will report the out-of-memory error later, a much preferable outcome. (cherry picked from commit 44a4abfd4f8695809eaec07df8eeb191d6e017d7)
