Subject: [PATCH 2/2] udev: optionally disable the generation of the
 'partlabel' symlinks

We already addressed bsc#1089761 to prevent the generation of
"primary" or "logical".

But it wasn't enough: some users could also have used their own
name other than "primary" and "logical" of course...

For them, we introduce "udev.no-partlabel-links" kernel command-line
option to prevent the generation of all by-partlabel symlinks
regardless of the name which was choosen.

This option should be *only* used to address performance issue related
to bsc#1089761 because it will be removed as soon as the udev
performance issue will be addressed.

[fbui: fixes bsc#1089761]
