Some modifications of vtermno were not done under the spinlock.

Moved assignment from vtermno and increment of vtermno together,
putting both under the spinlock.  Revert vtermno on failure.

Does it matter?  It's normal not to lock in a function called
"init_XXX", since it's not exposed yet.

Or is it?
Slight misnomer, I suppose.

We do this init_console_port() as part of add_port() if the port is a
console port.  Should it be named 'mark_console_port()'?  Dunno,
doesn't sound like the right name.  init fits closest.
