As suggested, the cond variable is really supposed to be a bool. So,
make it so.

gdb/ChangeLog:

2020-01-13  Luis Machado  <luis.machado@linaro.org>

	* aarch64-tdep.c (struct aarch64_displaced_step_closure)
	<cond>: Change type to bool.
	(aarch64_displaced_step_b_cond): Update cond to use bool type.
	(aarch64_displaced_step_cb): Likewise.
	(aarch64_displaced_step_tb): Likewise.

That looks good to me (and could probably be considered obvious).

Thanks,

Simon
