Fix Coverity 524: NEGATIVE_RETURNS

Coverity sees that two calls to tvb_length_remaining() with an offset
of 0 may return -1 (for an "out of bounds" condition), which would lead
to an assignment of -1 to an unsigned variable and then passing it
to functions further down that cannot accept negative values.

Use tvb_ensure_length_remaining() to throw an exception in a case of
out of bounds access (though unlikely with an offset of 0) instead of
tvb_length_remaining(), which would return -1.
