commit 8188a18ee2e48c9a7461139838048363bfce3fef upstream
We don't handle failures in the rb_allocator workqueue allocation
correctly. To fix that, move the code earlier so the cleanup is
easier and we don't have to undo all the interrupt allocations in
this case.

[Ajay: Rewrote this patch for v4.9.y, as 4.9.y codebase is different from mainline]
