disable blind subscriber insertion into every VLR/SGSN

During the attempt to fix OS#2785 in Change-Id
I6a92ca34cdaadca9eacc774bb1ca386c325ba865, we introduced logic that
would blindly insert a subscriber *concurrently* in all VLRs/SGSNs of
the network on any update of the subscriber.

Before that patch, we didn't update the current serving SGSN/VLR,
and after the change we created subscribers in all SGSNs/VLRs, of which
all-1 are not serving the subscriber at that time.

We'll have to go back to the original behavior until a proper fix can
be introduced.
