HNBAP De-Register should probably call hnb_context_release()

Description

For traffic counters, I needed a "hook" for when a hNodeB becomes inactive, so added a hnb_persistent_deregistered() to hnb_context_release().

The call chain on loss of the Iuh link includes hnb_context_release(), so that works.

However, I notice that hnbgw_rx_hnb_deregister() only sets a flag to false: that is probably not sufficient.

In practice, we hardly ever see a hNodeB sending a HNBAP HNB De-Register. Instead, they just drop the Iuh link.
Still, osmo-hnbgw should handle a HNBAP HNB De-Register properly.

Test this and fix if necessary.
