erts: Fix bugs in binary_to_term for invalid bitstrings
<<131, 77, Len:32, Bits:8, Data/binary>>
badarg if Bits > 8
Used to return internally inconsistent bitstring
badarg if Len==0 and Bits > 0
Used to return invalid *huge* binary (size = (Uint)-1)
badarg if Bits==0 and Len > 0
Used to return valid binary as if Bits was 8
