Log:
xpp: Fixes init error for PRI devices with < 4 ports

Fixes a regression singce r8873: if pri_protocol is not explicitly set
(in /etc/dahdi/xpp.conf) and the device has (licences for) less than 4
"PRI" (E1/T1) ports, the initialization script will attempt to read from
a non-existing SysFS file, and bail out, resulting in a the device
failing to initialize.

For those non-existing ports we can just skip that part of the
initialization. So we just skip it.

Work around: explicitly set pri_protocol to E1 or T1, as needed.

Xorcom Rev: 8047. Ticket: 1334.
