gbproxy: Avoid sending STATUS on unexpected BLOCK_ACK

Handle SGSN BVCs that are gone from the BSS differently.

The previous patch removed the gbproxy_bvc on the SGSN-side after it was
gone on the BSS-side. This caused a STATUS response to BVC_BLOCK_ACK messages
that should be valid. Instead of removing the BVC this patch marks it as
inactive so we can still handle BVC_BLOCK_ACK correctly, but ignore
other messages - especially BVC_RESET from the SGSN.
