[issue1872] nfs stall (fix pushed)

[Matthew Dillon]

    Thomas, please test the latest master or the latest 2.6.x.  I've fixed
    multiple bugs.

    The server bug existed on both 2.6 and 2.7 so you will have to upgrade
    your 2.6 server to test the fix.  I did MFC just the server cache fix
    to 2.6 so you can upgrade to the latest on the 2.6 branch
    (DragonFly_RELEASE_2_6), you do not have to upgrade your server to
    master if you do not want to.

    Please test.
