Ed Schouten 5db88944ac Remove unneeded Giant locking of /dev/tty. ...

The Giant lock is acquired in two places in tty_tty.c. In both places,
it is unneeded.

There is no reason to specify D_NEEDGIANT on this device node. The
device node has only been designed to return ENXIO when opened. It
doesn't make any sense to lock/unlock Giant, just to return this error.
D_TTY is also unneeded. The unimplemented functions don't need to be
patched by devfs.

We don't need to lock Giant when we want to lookup the proper TTY vnode.
s_ttyvp is already protected by proctree_lock (see devfs_vnops.c).
