RDMA/rxe: Allow registering persistent flag for pmem MR only
Memory region could support at most 2 flush access flags:
IB_ACCESS_FLUSH_PERSISTENT and IB_ACCESS_FLUSH_GLOBAL
But we only allow user to register persistent flush flags to the pmem MR
where it has the ability of persisting data across power cycles.
So registering a persistent access flag to a non-pmem MR will be rejected.
