IB/rdmavt: Support creating qps with GFP_NOIO flag
The current code is problematic when the QP creation and ipoib is
used to support NFS and NFS desires to do IO for paging purposes.
In that case, the GFP_KERNEL allocation within create_qp causes
a deadlock in tight memory situations.
This fix adds support to create queue pair with GFP_NOIO flag for
connected mode only to cleanly fail the create queue pair in those
situations.
This was previously fixed in qib but needed to get ported to hfi1.
This patch handles that for both hardwares in the new rdmavt common
layer.

IB/rdmavt: Add query gid stub
The handler for query gid operates along the same lines as the query pkey
handler. The driver will take care to keep the guid table updated.

IB/rdmavt: Add pkey query stub
The pkey table will reside in the rvt structure but it will be modified
only when the driver requests then rvt will simply read the value to return
in the query.

IB/rdmavt: Add query and modify port stubs
This patch adds the query and modify port stubs. The query will mostly
entail the driver returning everything in the ib_port_attr which will get
handed back to the verbs layer. The modify will need some API helpers in
the driver. The send_trap and post_mad_send are still issues to address.

IB/rdmavt: Add query and modify device stubs
Adds the stubs which will handle the query and modify device functions. At
this time the only intention is to support changing the node desc and the
