[PATCH 17/22] tty: vt: handle CSI+[ inside preexisting switch-case

[Jiri Slaby (SUSE)]

In do_con_trol()'s ESsquare case, there is already a switch (c). It is
preceded by an 'if (c == '[')'. Despite this 'if' handles a state
transition and not a modifier, move it as one of the switch cases. This
makes all the 'c' decision making more obvious there.
