lindev(4): remove the device

lindev(4) was only used to provide /dev/full which is now a standard feature of
FreeBSD.  /dev/full was never linux-specific and provides a generally useful
feature.

Document this in UPDATING and bump __FreeBSD_version.  This will be documented
in the PH shortly.

-.Os
-.Sh NAME
-.Nm lindev
-.Nd Linux-specific pseudo devices support
-.Sh SYNOPSIS
-To compile this collection of linux-specific pseudo devices into the kernel,
-place the following line in your kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device lindev"
-.Ed
-.Pp
-Alternatively, to load the driver as a module at boot time,
-place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-lindev_load="YES"
-.Ed
-.Sh DESCRIPTION
-The
-.Nm
-module provides a collection of linux-specific pseudo devices.
-.Sh DEVICES
-.Bl -tag -width /dev/full
-.It Pa /dev/full
-The
-.Xr full
-device always returns
-.Er ENOSPC
-on write attempts.
-For reads it emulates
-.Xr zero 4 .
-.El
-.Sh FILES
-.Bl -tag -width /dev/full
-.It Pa /dev/full
-.El
-.Sh SEE ALSO
-.Xr null 4 ,
-.Xr zero 4
-.Sh HISTORY
-The
-.Nm
-module first appeared in
-.Fx 8.1 .
