A-bis/RSL: fix dissection of Mobile Allocation in CHANnel ACTIVation
According to 3GPP TS 48.058 (version 15.0.0), section 9.3.5,
3GPP TS 44.018 "Mobile Allocation" IE shall for compatibility
reasons be included but empty, i.e. the length shall be zero.
It does not mean that the Mobile Allocation IE should not be
decoded by Wireshark though. Some BSC implementations may still
be sending it with length greather than 0.
Let's expose de_rr_mob_all() and use it in dissect_rsl_ie_ch_id().
If the length is greather than 0, raise a protocol warning.
