Subject: [PATCH] staging: et131x: fix allocation failures

We should check the ring allocations don't fail.
If we get a fail we need to clean up properly. The allocator assumes the
deallocator will be used on failure, but it isn't. Make sure the
right deallocator is always called and add a missing check against
fbr allocation failure.
