udev: remove rule for explicit creation of /dev/mapper/control

We used KERNEL=="device-mapper", NAME="/dev/mapper/control" udev rule to
create the /dev/mapper/control file. The "NAME" rule should be only used
to rename network devices, otherwise udev issues a warning message. The
device-mapper driver has proper DEVNAME=/dev/mapper/control propagated
in the uevent environment when it is loaded so we don't need further
instruction on where to create the node - udev knows already.

Also, these days, it is created directly by kernel inside devtmpfs.
This makes the NAME="/dev/mapper/control" rule completely obsolete.
