SVN rev 216430 on 2010-12-14 13:45:57Z by rmacklem
MFC: r216330
Disable attempts to establish a callback connection from the
experimental NFSv4 server to a NFSv4 client when delegations are not
being issued, even if the client advertises a callback path.
This avoids a problem where a Linux client advertises a
callback path that doesn't work, due to a firewall, and then
times out an Open attempt before the FreeBSD server gives up
its callback connection attempt. (Suggested by
drb at karlov.mff.cuni.cz.) The server should probably have
a 1sec timeout on callback connection attempts when there are
no delegations issued to the client, but that patch will require
changes to the krpc and this serves as a work around until then.
