    mount.nfs Fix error reporting for already mounted shares

    When mount is triggered for an already mounted

    share (using auto negotiation), it displays

    "mount.nfs: Protocol not supported" or

    "mount.nfs: access denied by server while mounting"

    instead of EBUSY. This easily causes confusion if

    the mount was not tried verbose :
