When VM migrate VMState of spapr_pci, the field(msi_devs) of spapr_pci
having a flag of VMS_ALLOC need to allocate memory. If the src doesn't free
memory of msi_devs in SaveStateEntry of spapr_pci after QEMUFile save
VMState of spapr_pci, it may result in memory leak of msi_devs.

Some memory allocated for fields having a flag of VMS_ALLOC in SaveState
may not free before VM load vmsd in migration. So we pre-free memory before
allocation in vmstate_handle_alloc() to avoid memleaks.

For some device state having some fields of VMS_ALLOC flag, they
don't free memory allocated for the fields in vmstate_save_state
and vmstate_load_state. We add funcs or sentences of free memory
before and after VM saves or loads device state to avoid memory leak.
