Queue depth calculations use a mix of work requests
and actual number of bytes. Consolidate all calculations
using minimum WQE size to avoid confusion.

If RTR WQE is posted and QP is flushed, a CQE is
incorrectly generated for the RTR WQE. Add code
to look for the RTR and not generate a CQE when
QP is flushed.

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.

The macros I40IW_STAG_KEY_FROM_STAG and I40IW_STAG_INDEX_FROM_STAG are
apparently bad - they are using the logical "&&" operation which
does not make sense here. It should have been a bitwise "&" instead.
Since the macros seem to be completely unused, let's simply remove
them so that nobody accidentially uses them in the future. And while
we're at it, also remove the unused macro I40IW_CREATE_STAG.

Some resources are consumed internally and not available to the user.
After hw is initialized, figure out how many resources are consumed
and subtract those numbers from the initial max device capability in
i40iw_query_device().

Include inline data size as part of SQ size calculation.
RQ size calculation uses only number of SGEs and does not
support 96 byte WQE size.
