audioctl: incorrect initialization of variable fields

[David Julio]

When u_int oldval was added to struct field, the initialization of
struct field fields[] became incorrect.

Example:
# audioctl play.seek=10
play.seek: 0 -> 0

Expected:
# audioctl play.seek=10
audioctl: `play.seek' is read only

Thank you for your time.
