savevm: fix corruption in vmstate_subsection_load().

Although it's rare to happen in live migration, when the head of a
byte stream contains 0x05 which is the marker of subsection, the
loader gets corrupted because vmstate_subsection_load() continues even
the device doesn't require it.  This patch adds a checker whether
subsection is needed, and skips following routines if not needed.
