[libvirt] [libvirt-php PATCH 2/3] libvirt_connect: use loop macros to read cred info.

[Dawid Zamirski]

Since addition of PHP7 the libvirt_connect regressed on PHP5 where it
was no longer reading out credential info from the php hash table
properly. This patch makes use of the loop macros that handle both PHP
versions correctly and consequently fix this issue.
