[PATCH] tty: vt: replace _manual_ swap with swap macro in set_selection

[Gustavo A. R. Silva]

Make use of the swap macro instead of _manually_ swapping values
and remove unnecessary variable tmp.

This makes the code easier to read and maintain.

This code was detected with the help of Coccinelle.
