udev rules: update the NAME= syntax to SYMLINK+=
    
    udev emits warnings via syslog over our use of the NAME= option in the
    rules file to create devices in /dev/infiniband.  Update the rules to
    use SYMLINK+= instead as that will leave the kernel provided device name
    in /dev and create our symlinks in /dev/infiniband, which makes udev
    happy and kills off the error messages in /var/log/messages.
