Pau Espin b0b76af0c3 SRVCC: Parse Last Used E-UTRAN PLMN Id in Handover Request
Whenever SRVCC EUTRAN->GERAN is performed by the CN, it will set the
Last Used E-UTRAN PLMN Id in order for the BSS to inform the MS
about EUTRAN neighbors once the call is over.
The last part (sending EUTRAN neighs) is already implemented, since same
thing is done as per CSFB. However, we lacked the first part, where the
EUTRAN PLMN Id is recorded for later use.

Actually, in both cases, we end up building the list of neighbors
without taking into accound the PLMN value (hence no filtering of
configured neighs), but it only sends such a list if any PLMN was stored
there, which means this patch is still necessary for a quick fallback to
4G after the call is over.
