Remove several ibport members from qib and use the rdmavt version. rc_acks,
rc_qacks, and rc_delayed_comp are defined as per CPU variables in rdmavt.
Add support for these rdmavt per CPU variables which were not per cpu
variables in qib ibport structure.

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.

In preparation for moving the queue pair data structure to rdmavt the
members of the driver specific queue pairs which are not common need to be
pushed off to a private driver structure. This structure will be available
in the queue pair once moved to rdmavt as a void pointer. This patch while
not adding a lot of value in and of itself is a prerequisite to move the
queue pair out of the drivers and into rdmavt.

The driver specific, private queue pair data structure should condense as
more of the send side code moves to rdmavt.
