Fix input length checking in SPNEGO DER decoding

In get_mech_set(), check the length before reading the first byte, and
decrease the length by the tag byte when reading and verifying the
sequence length.

In get_req_flags(), check the length before reading the first byte,
and check the context tag length after decoding it.
