[NETDIRECT] [PATCH 4/4] winverbs/netdirect: add support for inline sends

[NETDIRECT] [PATCH 4/4] winverbs/netdirect: add support for inline sends
By default, use inline sends, and allow user to limit
inline send size through an environment variable.

To support existing deployments, winverbs make use of the same
environment setting as the ibal ND provider.

Note: The kernel HCA drivers report 0 for the max inline send
value for user space QPs, even if inline sends are enabled.  I didn't
understand how to fix the kernel drivers, so they could report the
correct value.  The winverbs ND code simply returns the value that it
uses when creating the QP.
