RQ WQE size other than 128B is not supported.  Correct
RQ size calculation to use 128B only.

Since this breaks ABI, add additional code to
provide compatibility with v4 user provider, libi40iw.

Some resources are incorrectly organized and at odds with
HW capabilities. Specifically, ILQ, IEQ, QPs, MSS, QOS
and statistics belong in a VSI.

The flush_code variable in i40iw_bld_terminate_hdr() is obsolete and
the check to set qp->sq_flush is unreachable. Currently flush code is
populated in setup_term_hdr() and both SQ and RQ are flushed always
as part of the tear down flow.

Passed in page_size was used as encoded value for writing
the WQE and passed in value was usually 4096. This was
working out since bit 0 was 0 and implies 4KB pages,
but would not work for other page sizes.

Add support for QoS on QPs. Upon device initialization,
a map is created from user priority to queue set
handles. On QP creation, use ToS to look up the queue
set handle for use with the QP.
