[for-next 0/4] RDMA/ionic: add DMA MR and v2 atomic WQE

[Abhijit Gangurde <abhijit.gangurde@amd.com>]

Add a generic RDMA capability word to the LIF identity and use it
to allocate a PD-scoped DMA memory region. Use the v2 atomic send
WQE on RDMA version 2. Also fix the v1 atomic WQE so the operands
are not overwritten by the common payload.
