ns2_fr: Fix null pointer deref in error path
The followign happens if osmo-gbproxy is started without CAP_NET_RAW:
<0026> gprs_ns2_fr.c:515 BIND(hdlcnet1) Can not create AF_PACKET socket. Are you root or have CAP_NET_RAW?
gprs_ns2_fr.c:176:2: runtime error: member access within null pointer of type 'struct msgb' AddressSanitizer:DEADLYSIGNAL
the second line is free_bind() iterating overr the backlog while
destroying the not-yet-fully-initialized bind.
Let's make sure the backlog llist_head is always initialized properly.
