Valiation: suppress warning about uninitialized variables

GCC7 complains, though it's wrong:

 src/cborvalidation.c:472:57: error: ‘previous’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
 src/cborvalidation.c:485:61: error: ‘previous_end’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
