Steve, List
Please find a patch that stops us from leaking EDEADLK (not enough credits)
to userspace when we do not have enough credits due to a pending reconnect.
This can be triggered for example if the server responds with
STATUS_USER_SESSION_DELETED during the Create part of the Create/QueryDir
that starts a directory scan.
Easiest way to reproduce this is patching up scrambla to inject this error
every 3 directory scans:
