bgpd: Notice when we unlock if we should NULL pointer
The bi->net pointer that is being unlocked had a commit
that removed the `bi->net = NULL;` recently. This code
was preventing a use after free crash being experienced
in other code paths. While commit 37e679629f9 was fixing
a different code path crash.
Make the parent->net pointer aware it may be locked/freed
from multiple places and to not NULL the pointer to it
unless we have actually freed the data.
