winverbs/nd: do not convert timeout status value
wv_io_timeout is an error value, but nd_timeout is a
success value. This means that an overlapped request
can be completed in error, but GetOverlappedResult can
return a success value. Instead, if a timeout is fatal,
report the status as wv_io_timeout, but if the timeout
can be retried, then report the status as wv_timeout.

libibumad: fix setting mgmt_version when registering
umad_register takes as input the mgmt_version, but loses that information
when it calls umad_register_oui internally. The result is that the
mgmt_version gets set to 1, which is wrong for opensm support.
Fixup umad_register to set the mgmt_version correctly.

Allow a user to retry a connection request if it fails. Report a
'success' timeout value, rather than an error timeout, reset the

winverbs: allow WV:Disconnect() to be retried
ND for some odd reason wants a successful return code for
a failed disconnect call. If a Disconnect() call fails,
allow it to be retried. Return STATUS_TIMEOUT - a 'successful'
failure, rather than STATUS_IO_TIMEOUT, which is a 'failed' failure.
(I love Windows, really, I do.) A subsequent call to EP:
Disconnect() after a timeout will force the QP into the error
state and force the EP into the disconnected state.
This change is needed to prevent ndping and other ND tests from
reporting a failure. They only allow disconnect calls to fail
'successfully' with STATUS_TIMEOUT. With the status mapping
removed from the user space WV ND library, we need to return the
desired value directly from the kernel.
