libgfchangelog: Fix crash in gf_changelog_process
Problem:
Crash observed in gf_changelog_process and
gf_changelog_callback_invoker.
Cause:
Assignments to arguments passed to thread is done
post thread creation. If the thread created gets
scheduled before the assignment and access these
variables, it would crash with segmentation fault.
Solution:
Assignments to arguments are done prior to the thread
creation.
