Use Pool for BOOTP only

[Glenn Satchell]

The whole point is moot - since 3.1.0 failover works for dynamic bootp
clients. This is from the RELNOTES file:

                        Changes since 4.2.3

- Remove outdated note in the description of the bootp keyword about the
  option not satisfying the requirement of failover peers for denying
  dynamic bootp clients.
  [ISC-bugs #28574]

                        Changes since 3.1.0 (Maintenance)

- Dynamic BOOTP leases are now load balanced in failover.



So simply remove the 'deny dynamic bootp clients;' statement from the
failover pool and don't worry about the other pool or class.

I'm sure I remember something being posted to the list way back. The
current version (4.2.4) doesn't mention this in the dhcpd.conf man page.
You should always trust the current man pages over random stuff found on
the net, most of which can be quite old.
