hv: fix '(void) missing for discarded return value'

Browse Source 
MISRA-C requires that the function call in which the returned
value is discarded shall be clearly indicated using (void).

This patch fixes the violations related to the following
function calls.
- instr_check_gva
- vlapic_set_local_intr
- prepare_vm
- enter_s3
- emulate_instruction
- ptdev_intx_pin_remap
- register_mmio_emulation_handler

v1 -> v2:
 * discard the return value of enter_s3
