vlan: Remove unnecessary comparison of unsigned against 0

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

args.u.name_type is of type unsigned int and is always >= 0.

This fixes the following GCC warning:

net/8021q/vlan.c: In function ‘vlan_ioctl_handler’:
net/8021q/vlan.c:574:14: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]
