features/changelog: Capture "correct" internal FOPs
This patch fixes changelog capturing internal FOPs in a cascaded
setup, where the intermediate master would record internal FOPs
(generated by DHT on link()/rename()). This is due to I/O happening
on the intermediate slave on geo-replication's auxillary mount with
client-pid -1. Currently, the internal FOP capturing logic depends
on client pid being non-negative and the presence of a special key
in dictionary. Due to this, internal FOPs on an inter-mediate master
would be recorded in the changelog. Checking client-pid being
non-negative was introduced to capture AFR self-heal traffic in
changelog, thereby breaking cascading setups. By coincidence,
AFR self-heal daemon uses -1 as frame->root->pid thereby making
is hard to differentiate b/w geo-rep's auxillary mount and self-heal
daemon.
