hv: fix MISRA-C violations in vpci code: Function pointer is of wrong type

576S: Function pointer is of wrong type. C90 requires the elements of an
designated initializer to appear in a fixed order, the same as the order of
declaration. C99 relaxes this rule but seems MISRA-C sticks to C90 in this
regard.
