vmstate: fix buffer overflow in target-arm/machine.c
CVE-2013-4531
cpreg_vmstate_indexes is a VARRAY_INT32. A negative value for
cpreg_vmstate_array_len will cause a buffer overflow.
VMSTATE_INT32_LE was supposed to protect against this
but doesn't because it doesn't validate that input is
non-negative.
Fix this macro to valide the value appropriately.
The only other user of VMSTATE_INT32_LE doesn't
ever use negative numbers so it doesn't care.
