tty: simplify calling of put_pid.

This patch should contain no functional changes.

At some point I got confused and thought put_pid could not be called while a
spin lock was held.  While it may be nice to avoid that to reduce lock hold
times put_pid can be safely called while we hold a spin lock.

This patch removes all of the complications from the code introduced by my
misunderstanding, making the code a little more readable.
