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.
