This bug was filed from the Socorro interface and is 
report bp-90110b5b-a94c-4276-8044-ae9bd2140901.

This is the 26th topcrasher among D3D11-attempting sessions (prerelease channels on Windows).
Instead, return null. This way we will most likely still crash but in the NS_ABORT_OOM here;

Which is more meaningful for crash stats and reduce the number of bugs open for the same problem.

Tracking for 33 since this showed up as OMTC-related. Nical is this safe to uplift?

Approval Request Comment
[Feature/regressing bug #]:
[User impact if declined]: Some crashes on windows where we should have been able to recover without crashing (although failing to allocate a surface probably means we are low on memory, or something less fatal yet abnormal is going on).
[Describe test coverage new/current, TBPL]:
[Risks and why]: low, trivial patch.
[String/UUID change made/needed]:
