tun: revert fix group permission check
This reverts commit 3ca459eaba1bf96a8c7878de84fa8872259a01e3.
The blamed commit caused a regression when neither tun->owner nor
tun->group is set. This is intended to be allowed, but now requires
CAP_NET_ADMIN.
Discussion in the referenced thread pointed out that the original
issue that prompted this patch can be resolved in userspace.
The relaxed access control may also make a device accessible when it
previously wasn't, while existing users may depend on it to not be.
This is a clean pure git revert, except for fixing the indentation on
the gid_valid line that checkpatch correctly flagged.
