[git commit] vconfig: remove /proc/net/vlan/config check

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=be2a557918af86cc55b3426f97664503fe7e265f
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

In original implementation /proc/net/vlan/config check only prints warning
and does not exit. Busybox version exits if this file is not found and this
prevents kernel module autoloading to work.
I think it is safe to remove this check since ioctl() call will fail
(with proper
error code) anyway if 802.1q module is not loaded (or autoloading is off).
