IB/hfi1: Access hfi1_ibport through rcd pointer
Receive code paths use the QP's device and port
number to access the struct hfi1_ibport. When an
instance of struct hfi1_ctxtdata is present, it can
be used to access struct hfi1_ibport through a pointer.
This makes struct hfi1_ibport lookup time faster as an
array doesn't have to be indexed and access fields in
other cache-lines.
