hv: Change variable type to bool

Author: Peter Senna Tschudin <peter.senna@gmail.com>

The variable execute_shutdown is only assigned the values true and
false. Change its type to bool.

The simplified semantic patch that find this problem is as
follows (http://coccinelle.lip6.fr/):

@exists@
type T;
identifier b;
@@
- T
+ bool
  b = ...;
  ... when any
  b = \(true\|false\)
