Adjust the max_inline default size down so that it can be accepted on

multiple adapters (eg., Chelsio T3).

But we need to figure out how to determine a good value for the
resident adapter(s) at runtime.  It's problematic because, for
example, Mellanox ConnectX and Chelsio T3 report max_inline values
differently at run-time.  If you ibv_create_qp with a max_inline value
of 0, ConnectX reports back a value that is a formular based on a few
other values (e.g., max_send_sge and max_recv_sge).  But T3 always
reports back "64".

We're looking into this to figure out the best way -- reducing the
default right now should allow other adapters to run while we figure
it out.
