csn1: fix csnStreamDecoder(): skip bits unhandled by serialize()
This change fixes a bug that was reported by Keith Whyte and
confirmed in [1]. The problem is that a user-defined handler
in case of CSN_SERIALIZE may parse only a part of the given
bit-stream, leaving some bits unhandled. This is expected
because the sender (i.e. the MS) may use more recent RLC/MAC
message definitions containing new fields at the end.
Those bits that were left unhandled by serialize() shall not be
interpreted as continuation of the message, they shall be skipped.
Note that the encoded vector in the RLCMAC unit test still does
not match the original one. That's a known bug explained in [2].
