IB/hfi1: Remove unused struct mmu_rb_ops fields .insert, .invalidate 

The struct mmu_rb_ops function pointers .insert, .invalidate were only
used to increment and decrement struct sdma_mmu_node.refcount.

With the deletion of struct sdma_mmu_node.refcount and the addition of
struct mmu_rb_node.refcount  these function pointers are not called and
there are no implementations of them. So it is safe to delete these from
struct mmu_rb_ops.
