sh: intc: Initialize radix tree gfp mask explicitly.

Presently the root node is initialized by way of kzalloc on the parent data structure, which by chance happens to do the bulk of what an explicit initialization does with GFP_NOWAIT semantics. This however is more by luck than by design, and as we ideally want to permit radix node allocations access to the emergency pools anyways, add in the proper initializer with the desired mask.
