gbproxy: Restart IMSI acquisition on RA UDP REQ
Currently the IMSI acquisition is not restarted when a RA Update
Request is received. This leads to repeated N(U) in the generated
Ident Request message, which in turn causes the MS to drop the
second of these message. This is bad, when the first Ident Response
has been lost between MS and gbproxy.
This patch changes gbproxy_imsi_acquisition() to handle RA Update
Request messages like Attach Requests.
