bgpd: ensure that the node gets unlocked in all cases
The logic to unlock dest if iteration completed without iterating the
entire node was flawed. Specifically, if iteration terminated due to
`gr_deferred == 0` then the node would not get unlocked.
This change takes into account the fact that dest will be NULL only in
the case when the entire table was iterated and all nodes were already
unlocked. In any other case, it needs to be unlocked.

Modified BGP to pay more attention the prefix returned from
zebra to ensure that a LPM wasn't accidently causing BGP
import checks to think it had a match when it did not.
This unfortunately removed the check to handle the route
removal.
This sequence of config and events would leave BGP in a bad state:
ip route 100.100.100.0/24 Null0
router bgp 32932
bgp network import-check
address-family ipv4 uni

still think the route existed:

With the simple BFD configuration -
(active mode, single hop, without other parameters)
```
!
bfd
peer 11.11.11.11
exit
!
```
The interface with 11.11.11.0/24 is a *virtual* interface,
which can be deleted.
After BFD FSM is created and session is ok, do these things:
1) delete this interface
2) create this interface
3) set same ip address in this interface
Now, everything seems completely restored because all configuration
is same. But bad thing happens, BFD session hang on "down" status -
```
root# show bfd peer 11.11.11.11
BFD Peer:
peer 11.11.11.11 vrf default
ID: 638815827
Remote ID: 0
Active mode
Status: down
Downtime: 3 second(s)
Diagnostics: path down <- caused by destroyed interface
Remote diagnostics: ok
```
With the interface creating, `bfdd_sessions_enable_interface()`
wrongly compares added interface with the created, even key of
this `bfd_session` isn't binded with any interface. So this
`bfd_session` will hang on "down" status for ever.
So skip the compare in this case (no interface in key) to wake up
this `bfd_session`.
